The Sci Guys: Science at Home - SE3 - EP9: Simplest Electric Train - Magneto-Electric Train
ฝัง
- เผยแพร่เมื่อ 25 มิ.ย. 2015
- Welcome to science at home episode nine, season three. In this episode we will be building the simplest electric train. The simplest electric train is another type of homopolar motor and it can also be called a magneto-electric train. The simplest electric train works by harnessing the magnetic field generated when a current passes through a coiled copper wire, to push and pull magnets on the train. This train is homopolar because its polarity is constant as it functions. By the end of this video you will be able to describe why the train moves, how magnetic forces can be used to do work and how to build the simplest electric train also known as a homopolar motor or magneto-electric train.

Thank you i did this experiment for the science fair in my collegue
That was nice explaination👍
Best video shows why simple electric train go ahead. We know how to fix it faster
2:38 is copper coil necessary for movement or can I use a copper plate which is bent like a disected pipe
Can diameter of wire has any effect on the overall experiment or does it should be between 14 to 18 gauge only or thin dia wire can do the job
i love it is cool experiment
Do an explanation on curcling magnets please
Will there still be friction though?
Would it work if you just put the magnet battery through copper pipes
Can this work with a 24 guage wire?
What would happen if you connect both ends of the copper wire?
Johan Ferreras If you to it just right, the train will continue travelling in a circle.
If you connect both ends of the wire, is it the one that is called toroid?
Hi, will this work with two magnets glued south-to-south inside an enameled wire tube with an external power connected on the ends of the coil? Seems like a simple question, but I can't seem to figure if the forces outside the magnets will cancel those inside resulting in no movment.
I was wondering the exact same thing, please answer this!!! Based on this explanation, it should be possible to stick the magnets on either side of an insulting material with this orientation, and have an external power source run a current through the wire. I am hesitant to say this will work tho
@@feelthebluesgaming7630 I posted this question a long time ago. Now I know this will not work. The force created by the magnetic field of outside poles going through the current-carrying coil cancels the one created by the inside poles perfectly.
where did u get your bare copper wire from?
plz reply fast, need it for science fair project
+Patience Patience Well we found it at a hardware store, specifically Home hardware but you may need to google or call around. Hobby shops may sells it or renovation stores.
interesting!
How fast does it drain the battery?
Do you have to use rare earth magnets?
I know this is an older video but would the inverse of this work for example, instead of the magnets being a attached to a battery say a piece of metal rod, and then applying the electric current to the coil itself
I know this is an older comment, but I think a magnet is still required in the setup to do stuff
Will it work with a solid copper tube ?? Just curious…..
Isn’t the visual bar magnet orientation at 4:35 wrong?
I doubt the push and pull theory, it spins! Isn't there anything to do with the friction? Or spin and p p?
I have a question. Can you do this in a way to make it like an elevator? If so, what do I have to add/change?
Please respond quickly
+Juan Rojas you probably could but you would probably require more electricity and stronger magnets.
thank you, I'm working on a project so this is very helpful!
@@kriegddf9583 How did it go, bud?
Should magnets touch the wire
Yes
The Simpsons' Valentine's day card :P
Facu Pasini Yup
How fast does it move?
What would happen if there were only one magnet at one of the poles? You said that one magnet needs to act as the "pull" and one as the "push". So if there was only one magnet, would it simply be a weaker movement because there's only a "pull" or would it not even move? That's my first question
Secondly, I'm assuming that the magnetic field in the coil only exists on either end until half each magnet. Otherwise if the South Pole of one magnet is attracted by the field, the north pole of that very same magnet should be repelled by that field, leading to no motion. So we are to assume that the field ends before the outer extremities of the magnet?
If you have magnets only at one side of a battery you would not have current because only magnets at both side create closed loop for a current to flow. Magnets here act as a conductor.
can we creat a little bit push using metals instead of magnets
can i use any type of magnet of the same size used in this video
reply fast
and please tell your material used in this video to
+Ankit Mukherjee the material list can be found in the info of the video and on our website. They need to be strong rare earth magnets.
Do u guys post videos when u have time, or is it on a schedule?
jaden cavan We normally post a video every couple of weeks. We had a delay in this recent episode because Ryan and Theresa's baby was born a few weeks and go. Since Ryan does the editing and animation, things got a little delayed but we are working on getting back on schedule now. We have a lot of fun ideas for the summer and a really big 10k subscriber video that will come out around the time we hit that goal.
The Sci Guys tell Ryan that I said congratulations!
jaden cavan Thanks!! This is Ryan :)
The Sci Guys do u have Instagram? If u do, follow freestufffinder because she posts awesome deals for things including baby food or formula.
Does this usage depolarize the magnets faster?
Would this work through a solid copper tube?
+Mike Jacobs I don't think so. I think it needs the loops to generate the correct magnetic fields.
how to identify the north and south poles of the magnet
Can we use aluminum wire or iron wire for this project
The wire required for the experiment is coated magnetic copper wire.. Find it here amzn.to/2BBVS5O
What is the diameter of the neodymium magnets? Also, why do you need 14-18 gauge wire?
EternalRhapsody They are just slightly bigger than a 'AAA' battery. We chose 14-18 gauge wire because it was thin enough to make nice smooth loop and because we could make a lot of loops close together. At the same time it's thick enough to support the battery and magnets.
@@TheSciGuyscan I use 20 guage wire for it? Please reply faster I need it for my project
i think you messed up the polarity of the magnets at 3:12. Great video elseways!
Anton Anthony Why do you think we messed up the polarity of the magnets?
+The Sci Guys I noticed it, too. The graphic shows two magnets' south poles attracting to one another while the attractive force between opposites is explained. Making sure we're paying attention?
h7opolo Anton Anthony Well....didn't notice that. I thought you meant the positioning of the magnets on the train. The magnets on the train are correct but you're right we goofed on the poles explaining that opposite poles attract at the top of the screen. It's too bad that we missed that but since we cannot fix it, I will add an annotation to point it out :)
How many meter is the wire?
That is a very good clip. My son followed your video but we don't know why it is not working. We have neodymium magnet, bare copper wire and 1.5 v alkaline battery. We made sure North side of magnet pointing outside. But the train was not moving inside the copper wire. Do we need to wrap around copper wire very tight? You don't want the gap in the copper wire is too big but it is hard to make a very tight coil by hand. I wonder whether the gap is the reason that our train was not moving. Please help. My son's science fair project is due next week and we would love to show this to the audience if possible. Thanks!
+Roy Xu I would say that the gap may be the issue. We had gaps and it would sometimes fall in between and break the circuit. Also make sure you are using a AAA battery because it's smaller and lighter than a AA battery. It was tough for us as well to wind it tight and mark had to really force it together to keep the gaps as close as possible. You may want to try a slightly thinner wire because it may be easier to wind tightly. Also make sure you are using a fresh battery. Those are my best suggestions.
What if we wire of different gauge??
What if use an li-ion battery instead. Would it go faster?
i made the same experiment but unfortunately, the battery does not move. can you explain what mistakes that i might do?
+Nurul Iman There could be a number of reasons. The magnets may need to be flipped, the coil may need to be closer together or the battery may be out of power.
can we use use aluminum instead of copper for this?
Well it would work but not as good as with cooper, because Al is paramagnet material when Cu is diamagnetne material. Paramagnetic substances are characterized by the fact that the magnetic moments will be partially directed in the direction of the external field, which causes a slight attraction between the coil and the train. Whereas diamagnetic substances are considered to develop a weak magnetic moment opposite to the direction of the external field and will be slightly repelled by the magnet, which will help the train move more smoothly.
So in the short it would work but not as good as on the video.
I hope that would help you and also I wish you as much success and experimentation as possible.
Is it okay to use one magnet on each side? Please reply fast
No, you should use multiple
Can you tell me why aluminium wire isn't used for this? We were able to get the copper wire to work and make the train move forward. Then using the same gauge (18) aluminum wire and same battery, it seemed to reject the train and moved slightly backwards.We are having trouble finding why this might happen.
Presumably aluminum wire is applicable for this application.
The resistivity of (industrially pure) aluminum is slightly larger than the resistivity of copper, but not much different from copper.
Of course, there are some shortcomings in the use of aluminum wire.
First, the mechanical strength of aluminum is lower than that of copper and it is easily deformed by the externally applied force.
Second, due to the thin oxide film on the surface of the aluminum, the contact resistivity between the wire and the (nickel coated) neodymium magnet can be slightly larger in the case of aluminum.
Either way, I think you can use it.
Perhaps the direction of the windings is reversed?
Please try to flip the direction of “the battery train”.
@@yoichihirose3806can you please tell me if the copper wire is insulated or non insulated please?
how thick is the copper wire need to be? and where can I get this magnet? also what is the magnets real name
+Cyril Padayatty We found the magnets at a local hardware store that sold them for cabinet doors. You can use 14 to 18 gauge wire. I think in the video we used 14 gauge .
Neodymium magnets were used in another video
Can we use any earth magnets
+Arsh Bandlish They need to be strong earth magnets. The stronger they are the better they will work and if the magnets are too weak they won't work at all.
can u tell me that why we don't use any other magnets than neodymium magnets??? pls reply fast...
+ronit roy Neodymium rare earth magnets are much stronger than normal house hold magnets.
I have been told that they have been created by a scientist
Can it also work with electro magnets?
Zaydmuhu Ghori Do you mean replacing the battery with an electromagnet?
Yes
Hi
The Simpsons Valentine's day card :p
doesnt it work with other magnets because of the strengh?
+Mia Crivitz If the magnets are strong enough they will work in this experiment.
even ferrite magnets?
Mia Crivitz I am not sure. We didn't test it with those.
@@miacrivitz9528 any rare earth works, but I would say neodymium ones are best
Why we using magnet here what is a reason ,is it battery(dc current) increase the magnetic field
I had fixed all the magnets in correct manner but still I'm totally failed sir.. please guide me about wire's looping distance and all about it..
please reply fast sir..
Have you used enamelled copper wire amzn.to/2BBVS5O
🙏🙏copper wire is insulated or without insulation???plzzz tell 🙏🙏
You got the answer?
what is the broom stick.....is it magnetic or non magnetic
+aditya singh The broom stick is just a normal wood broom stick.
+The Sci Guys lol
how come this isn't working for me? The wire is bare copper. Tried all possible magnet orientations. Could magnets be too weak/small? They appear to be very strong otherwise. Even if they were a little weak, at least there's be some pull. But instead, absolutely nothing happens for me.What could I be doing wrong.?
On what concept does this train works on ??
Please let me know ☺️
I want to create a project on this model ,,, if possible can you give whole concept pdf. So that I can work on it . 🥺
Hi I'm working on a project on this train too, can we contact each other ?
can we use normal magnets?
LowLCuber no only earth magnets Witt work
No only rare earth
12mm×1.5mm neodymium magnet is ok.......plz reply fast as I need to buy them
+aditya singh A neodymium magnet should work well. The size should be the same or a little larger diameter as a AAA battery.
@@TheSciGuyshow about 15mm?
Pokemon! We love Pokemon.
+Joelle Daddino Pokemon is great!! but not the show we were talking about :)
+The Sci Guys that quote was from Pokémon and then the Simpsons referenced them in that episode
+Drastar Striker The episdoe of simpsons we were referring to came out a lot before Pokemon was in North America and I think before it was produced in general.
Pokémon was created 2 years before it launched in North America
The Pokemon comment was from my 11 and 7 yr olds. They have NO IDEA who The Simpsons are. So for them it is from Pokemon and for you guys it is The Simpsons. They loved it though. And they LOVE The Sci Guys!! We watch it daily as part of our homeschool science study and try many of the experiments. They love the bloopers too!
hi sci guys!! i am planning to do this simplest electric train in our upcoming science fair and i was wondering where can i buy those kind of magnets?
please reply as soon as possible, i really need your help (T.T)
+Jerley Quiambao We found our magnets at a home renovation store. They were sold as magnets for cupboard doors.
that's a big help, thanks!! :D
i was wondering if having a different color or thickness would change or affect anything? hope you reply soon :D
We made the simplest electromagnetic train and covered other electromagnetism projects here: th-cam.com/video/W1hJ217-g_E/w-d-xo.html
What theory of physics does this shows?
Electromagetism the force of magnet field pushes the battery away from the coil's electric field and the cell moves like a train
I have normal magnets, can i cover them with aluminium foil?
P.s mine is not working.
+Yajur Phullera Why would you want to cover the magnets with aluminium foil? The key is having strong magnets and a coil that is tight enough that the magnets won't fall through. It took us a few tries to get it to work but if you don't have strong magnets it won't work well, if at all.
+The Sci Guys okay thanks. I have made with neodymium magnets. 😊😊
i tried to make it but its not working:( I made the setup correctly as u explained but in vain.
dont know what is the fault, i guess it is the magnets. i used some magnets which seem to be strong enough, not sure if they are neodymium. plz help!!!
+Niharika Sharma hi! make sure you use alkaline batteries
and the magnets repel each other (make sure the its the south poles that's near the batteries although you cant really identify which is which so just make sure the magnets doesnt attract each other)
and make sure the copper wire you use doesn's have any enamel coating.. try watch the video of amazing science :D
+Niharika Sharma Jerley has some great tips. Also make sure you use a fresh battery.
how to recognize a bare copper wire?...
+ronit roy bare copper wire has a copper colour like in our video. If wire is insulated it will have a bright coloured insulator coating like plastic.
why do my magnets stick to the coil?
why only alkaline batteries used??? reply fast anybody...
+ronit roy Well you could use any batteries I guess.
It's not working why?
we tried to do it but it is not working. we put copper around broom and had aaa
and magnets strong earth. what else do we have to do?
+Amber Noble Try flipping one of the magnets and try putting it in both sides of the coil. Also the loops in the coil may need to be closer together.
thanks i will try and how many magnets do we use
+The Sci Guys thanks i am using it as science project
I know it's too late..😛 but did it work for you?
that quote was from pokemon
+Drastar Striker Nope :) It's from a valentines episode of Simpsons.
which was from Pokémon,
"Pikachu, I choose you!"
Sir I am making this train in my school science exhibition but the problem is that my train is not working please guide me in making this electro magnetic train
Have you used enamelled copper wire. Find it here amzn.to/2BBVS5O
The Simpsons?
jaden cavan you are correct sir :)
Ralph Wiggum's valentine to Lisa. I'm so old...

But where is that from?
Pokemon!!
De Indiaaan nope not pokemon :P
De Indiaaan lol thought the same. :)
excuse me there I got confused in the magnet session??? I read a article about this and it says one end of the battery becomes south and the other becomes a north end but I didn't really got the meaning because I didn't get how do they figure out which end of battery is south and which one is north. So I want u to look at this photo from the article please help. skullsinthestars.files.wordpress.com/2014/12/trainexplanation.jpg
My not working please tell
Попробуй по переставлять магниты , скорее всего перепутал полярность
it is pokemon
which is a fool guy which give dislike
I did everything right a 1.5 V battery 4 rare earth magnets 2 on each sid and a copper coil but is still not moving tried evry position of the magnets!! can u help me?
fast plz!!
+Avighna Jha try making the loops closer together or repositioning the magnets by changing the pols. We had to play around a bit before we could get it to run smooth through.
+Avighna Jha if you are still having good trouble message us on Facebook.
@@TheSciGuysheyy i am also having trouble can you help me?
did it work for anyone?? I have to try it for my science project...I don't have time to do all the things..if it doesn't work my whole time will be wasted..
Does anyone made this?
I need guidance pls help me...i dont want to waste my time
The Simpsons right?
Emma Brush yup :)
Means it is not perpetual.

Guys this video is photoshopped.
1) firstly the neodyium magnets have to touch both the upper part of the coil and the lower part . In the animated part of the video they said the exact same thing however if u look at the function of the train it does not portray the given thing . So it's photoshopped
Very bad explaination
