2:11 who hurt you dave
What?
ThinkTractions he said amazing huh instead of pretty cool huh
I was also stunned by this.
@ThinkTractions you ain't OG.
@@thejordyoshi ikr I was hurt, where did "pretty cool, huh" go🤔?
Some very important bits of information that were missing from this video:
- The magnets pretty much must be neodymium types. Some 'refrigerator' magnets of the same size, shape an appearance will not be string enough to result in a working motor.
- While most round neodymium magnets are polarized with N on one face and S on the opposite face, there are indeed identical looking neodymium magnets that are polarized 90 degreed out from when it necessary, and they won't work.
- The copper wire must be conductive at all points where it touches the end of the battery, and also where it touches the magnet(s). The wire can be plastic insulated or lacquer insulated for the rest of its length, but it is usually best to use completely uninsulated wire.
- There MUST be an electrical circuit, with current flowing from the tip of the battery, through the wire, and back to the opposite side of the battery via the conductive nickel plating of the magnet(s). It is a LOT of current, as the battery is essentially being short-circuited. Larger batteries can produce the same amount of current for a longer period of time, so a "AAA" cell will last longer doing this than a button cell, a "AA" cell will last even longer, a "C" event more, etc. But regardless, the run time is not very impressive, and a partially drained battery/cell either won't work at all for this, or else the wire will spin slowly.
- It should be clear from the above that the wire must be making an electrical connection with the magnet(s), but you want to form the wire so it is pressing against the magnet with just enough pressure to assure a good electrical connection, but not any more pressure than that, or the friction will slow the motor down.
string enough?????
The nerd at school be like 😂😂😂😂
does the amount of magnets u put affect how fast it is?
excellent comment, ty!
Could you also perhaps explain the function of the magnetic component in the circuit? If I could somehow get the wire from the positive to negative end of the battery do you think it'd still be functional?
this channel didn't devolve into fake lifehack channels over the years. I'm really impressed! keep up the good work!
What are the odds that I'm fidgeting with a battery and getting a youtube notification about a battery toy video? 😂
Ha ha!
Its happening more and more. I told a staff member to buy some silica gel and he said ok and the Same Day a video about it popped up..

@@DaveHax wow😱
When he said “pretty cool huh”
I felt that
It is 7h11 in the morning ,South African time.I finished my New York wordle game and this is my first best video for today .Thank you.Can't wait to try it.Vetri South Africa 🙏🇿🇦🙏
"Amazing, huh?"

@Ibraheem 2427 YES RUNNNNN
@Ibraheem 2427 GO TO THE (totally NOT wobbly) BRIDGE!
I JUST remembered about this channel after not seeing a video in YEARS after a little bit of trying searching finally found it. I absolutly LOVE how everything is still the same, same songs, same calm voice, same style. I loved hearing again "Pretty cool, huh?".😍😍😍
I dont know what science is behind it
me too bro
Pretty cool huh
❤❤❤
What is your catchphrase
"Pretty cool huh?"
Or
"Amazing huh?"
Pretty amazing, huh? ヾ(❀╹◡╹)ﾉﾞ
Pretty cool huh?
Pretty 🅱️, huh?
Omg you are so right !!! 🤣🤣😂😂😂😂
Pretty 🔋 XD
I did this for my science fair project.I won!!
Really?
Good job
Congrats
That is amazing
That's pretty cool huh! Kudos🎉
Science is an interesting and amazing thing. For me to invent something would drain my brain just coming up with something fun. Great video mate
Very cool and useful, forget boring physics with Dave!
basic electrical and magnetic fields best demonstration 😎✌
Wow, very impressed 👍👏
That is actually so cool!
Finally, someone found the starting point of making ufo
U can make your own game with just battery and wire, I love it
i made one of these homopolar motors - and it is sooo cool - simplicy and magic in one ✨
this is really great visualization of how battery and magnetic fields interact. I always love to see science experiments to see how stuffs work.
I get a charge out of watching your videos every time.😄 Nice one!
Good joke, bud
Nice motors! I'd like to see a short, where you do it with thicker wire, and an F-Cell battery. F-Cells can be found in 6-Volt lantern batteries, and I'd recommend getting an Energizer-branded lantern battery, to get 4 of them. Just be a bit careful, cutting off their connection tabs, once the F-Cells are cut out.
You're such a genius
When this lockdown is over, I will get down to the electronic shop and get the copper wire and give this a try. I think my grandson will love it. Thanks for video 👍
I'm from 1 year in the future. The Lockdowns continue..
That is bloody awesome! Thank You for posting this!
I personally adore your egg slicing and hot knife cutting videos please please please do more. I love you Dave.
It works with cable wire too. You may need neodenium still. But it worked with my neodynium cubes
Very cool, Dave. Nice video.
This was so cool!
I tried making this many times before and it was a success. If you flip over the magnet, it would spin the other direction.
Can i know how to make it spin? Cause i tried but it didn’t spin🥲
@@lunainluv u need to make the bottom loose enough so that there's less friction. But when u put the wire on top, u need to make sure part of the wire touches the battery so that it moves. If it still doesn't work then idk the problem for u
Excellent ideas. Watching with full support from Canada 🇨🇦.
Very nice project 's you are a genius
Now that i know this imma make me something really cool. its gonna be such an epic art piece!🎨
nice video what gauge copper wire are you using .for this project.
Great video lad keep up with the good work
Use rechargeble battery, they can produce up to 10 times bigger current! Motor will spin much faster! :)
Cara...isso foi muito bom!
The wire can't spin . Thought I done as you done in the vedio.
Nice experiment !!
Why am I picturing a fabulous bear dancing on the ice?

@@Nuttyirishman85 Mexico was the LEADING country in destroying the Japanese convoy coming to America! Alot of good men died in them fields my little lad!!
Oh pretty cool. I did not make one but I would like to ask question . How much time it is working ?
awesome video
Them are cool little Motors it gets your mind going I've been messing with motors and lights ever since I've been a little kid
Kids at the next science fair should write you thank you notes... You just gave them the best demo project...
My favourite video!! Il love dave hax!❤❤❤💓
*Amazing Huh?*
Nice video Dave😀
Your life hacks are pretty cool
I love you DaveHax!
Someone did well in school 😂😂😂 love your channel keep up the good work
this battery 🔋 so cool 😎
Dave hax 2019 : "pretty cool huh?"
Dave hax 2020 : "amazing huh?"
2019: :D 2020: :C
What gauge of wire works best for this project?
I remeber watching you years ago , the video i first watched was the Halloween one anyone remeber ?
Hey Dave, try attaching razors to wire and a really powerful battery and cut some cucumbers!
If someone was to do this with a very powerful (for instance neodymium) magnet, would it make the wire spin faster? Or will it cause anything dangerous to happen? I googled it & it doesn’t seem like there’s any kind of well-discussed contraindication between (at least lithium) batteries & magnets. But the discussion was mostly around whether it would drain the battery. I was more concerned about whether it could heat up and/or explode the battery lol.
I made this exact experiment using neodymium magnets,and it spins really well. The flat magnets the author is using are neodymium. Ive got the same magnets and a $hit load of various sized Neodymium magnets.
This experiment is great.A lot of fun...BUT,you wear magnets out rather quickly.It gets expensive.
One note...
Batteries are a DC source.
So,I tried this with DC transformers of varying volts and currents.I couldnt get it to work.A bit of a mystery to me.
Oh...and as far as batteries exploding...Ive killed many batteries playing around with this,and never had one to explode or even get hot.
@@stegususcley2655 Don't you mean, wear out batteries quickly, not magnets?
Nice im gonna try😁😁😁
Helpful experiment...so nice of you.. We are also doing such experiments....
Thanks a lot for the video
How does the current flow when the wire contact only one pole, the + ?
Cool great shapes 💡
What could be the reason mine is not spinning? Need stronger magnet?
Parents: so you failed the exam
Me: pretty cool huh?
Does it have to be copper wire specifically?
Why am I watching this videos instead of doing online school
@@korbynludlow4926 I said that like a year ago lol
🌷🌷Really amazing sir
That soo good 😍
Yes, that's cool.👍
Pretty simple huh !!!
2:48 it looks like a force field
Does it only work if the wire is around the magnet at the bottom? Or would it work with a shorter piece of wire

Hi Dave, this is not working , what of magnetic you used
"here's a really cool spiral one i made" XDD thank you so much
Finally I can finish my science project
If only the Earth was electric in nature and we could harness free energy to create something similar to this on a larger scale...
Oh wait, it is, and we can. Tesla was trying to show us. Carry on.
what kind and size of magnets does it need to use to do that??
Pretty cool I think I will do this with my grandson he'll get a kick out of it.
what magnet you use?
Perfect dave hax hes so smart
i agree
Where i can get the magnet 🧲?
Для тех, кто не знает школьный курс физики это выглядит фантастикой
Your hax are pretty cool huh?
does the battery have to be circular?
Came here after reading about DIY motors in Dr. Stone. Cool!
Mr wizard used to do stuff like this . Great to see physics at work
Does the battery ever burnout or lose energy
thank you
Where can we get those magnets and much does it cost
Back ground music issss ssoooo nostalgic 😭😭😭 i supposed to watch u when i was between 8-11 best channel evrrr
I liked the old bgm
Why all people dislike this idea intelligent boy --battery and magnet make motor is nice
Awesome
What kind of batteries did you use
Woah! 100 likes in the first 2 minutes of release! Shows how amazing dave is!!
Haven't you already made these before in a valentines video
Amazing
This mans voice is like a anti-stress thingy
You are a nice guy
