Magnets are mostly known for their magnetic force, which is very useful in itself. But magnetism is also useful for many other things. In this video I give you a look at just how effective magnetism is for heating food in induction cookers. And how the magnetocaloric effect may be used to magnetically refrigerate your food in the future!

#induction #magnetocaloric #Brainiac75
considering you are magnet king of youtube. have you ever tried building a planar magnetic mini speaker ?
No, I haven't. But it could be a nice project for a future video. Thanks for watching and the inspiration!
I worked in metrological thermometry, and as soon as I heard “Pt-100” I was like “heeyyyyyy”
I admit I was a bit frightened to see it snapping to the magnets like that. I had to be extra careful while handling them, as any audible shock at the tip, even a tiny one, was likely to destroy their history. You basically had to send them back for recalibration, and that ain't a cheap commission.
Didn't know they were so sensitive! I know them as relatively cheap go-to temperature sensors for your average DIY project :D
@@Mezgrman they can be it all depends on whether you are trying to measure a 2 Kelvin or a 2 microKelvin difference
Cool channel with hot contents attracted me here.
Hehe, I think you are a cool dude with a warm heart. Thanks for watching and commenting!
Wow your channel has grown a ton Brian! I can't believe so many people are interested in magnetism! Awesome!!!
I have a serious issue with your videos that I don't think even you can, or want to fix.
They're so interesting and in depth that 11 minutes flies by like a minute and I'm sitting here hoping for more. Thank you for such informative and interesting videos, keep up the great work!
Well, I would actually like to make shorter videos, LOL. This one took what feels for ever to edit. Those 16 magnetic moments are hand-animated x) But I am glad to hear, that my hard work is appreciated. Thank you very much! More to come.
@@brainiac75 I have no idea what goes into the editing process as the last time I edited a video of any kind was a high school project for AV club back in probably 2000. And that was on cassette tapes.
But yes, your work is very much appreciated by me and probably a whole bunch of other people.
Thank you for the effort you put into it.
I'm always so excited to see your vids!
Never disappointing, thanks for the great science demo!
Glad to hear this one didn't disappoint either, Big Iggy. It was a lot of editing.... Thanks for watching!
@@brainiac75 no *Thankyou!* Seriously, cabin fever has been driving me nuts! Not to mention, you always have fantastic experiments!
I'd like to send some chemical elements to you btw. I sent some to Cody don from Cody's lab, and I'd like to send some to you as well. I have very fine, laboratory pure copper "sand" and I was wondering if you wanted to pour a sample across one of your huge magnets?
Been using induction for over a decade now, and it has a lot more control, less inertia and perfect control of the temperature. And I even have a "portable" induction cooker for outside and it has a temperature management for milk, frying, deep frying and boilin water. It's always and the correct temperature.
These vids are awesome. I show them to my sons. We enjoy watching and learning about science. Thank you for posting them. Please continue. 👍🏻👍🏻👍🏻
I started watching your channel because of the laser video's, i subscribed because of all the fantastic content you have, you also have a very calm voice which is always a nice addition to videos, alot of people are very hyperactive on youtube these days. Your channel is fantastic!
Another great reason why I love magnetic induction! its quick, energy efficient and cool to use!
Not cool, hot.
Absolutely! I will without any doubt switch to induction cook tops when my current stove burns out. I will however need some better cookware. The ultra-cheap cookware I bought for the two latest video have a horrible, high-pitched whine on the induction cooker. Bad bonding and design I guess. Thanks for watching and commenting so fast once again!
Why is the voltage so low in your house? Aren't there devices that would just refuse to run on a voltage that low?
Most modern psu works from ~90V to ~250V. But still, definitively he's on the realy low side.
The local / street substation will be overloaded.
As he saud, 3phase power source so 208 is normal in the US but house power is normally single phase and runs 240 VAC or 120Vac for my house. I hope this helps.
2.48 heating plates on your stove are also "just" 230V and somewhere in between 5-9 amps each. Stoves in Denmark typically receive 3 phases. But each phase goes to a different part of the stove. Phase 1 to two of the heating plates. Phase 2 to the other two heating plates and phase 3 to the oven. All 3 sections run on 230V
This is very detailed and extremely useful for some. I give the video a thumbs up I never give videos a thumb down. I actually don't really understand the concept. Anyway I would have loved to have seen a less detailed version because when I saw the picture I thought okay he's going to explain how much power and and how fast and the amount of energy that it takes and the efficiency factor.
Maybe you could do a 7 minute or 5 minute follow up video just including these things for the less sophisticated amongst us (meaning me)...lol
That's really neat! Thanks for the video.
Bismuth should show warming from a magnet. Very slight. Strongest effect will be near the top/bottom edge, the rims of the magnet.
Today's my birthday so I really enjoyed this birthday of a video,I love all these videos,I just wish I could be a patron for you
I'd like to see a comparison of induction vs natural gas. The cost difference will definitely be relevant but that's specific to what is available to you. I'm asking about time here.
Crazy thought... I wonder... how Giant or smaller magnet will react on induction cooker? Atract, vibrate or demagnetise?
I imagine that induction cookers run a lot of field lines in changing directions next to each other, so the magnetic forces cancel out over the whole surface of the stove. The magnet would likely just be heated like any other object, but when permanent magnets are heated, the material gets softer, allowing the magnetic particles inside to rotate so the magnet is demagnetized.
The power consumed by a resistive heating element doesn't vary as much with voltage as you implied. The heating element has a positive temperature coefficient of resistance. Which means it tends to compensate (at least a little) for voltage variation. At a higher voltage than you were running it at then it would have become hotter, which would have increased the resistance, which would have decreased the current, which would have decreased the power, which would have lowered the temperature.
can you do more vids like this?, i would like some performance test of more housewares
I learn so much from your videos everytime. Thank You
Glad to hear! Thanks for watching and commenting :o)
9:30 i need a quiet fridge. this technique sounds promising.
0.1°C = promising? it's a phenomenon that is barely measurable
Well it isn't quiet but you could get a chest freezer and turn it into a chest fridge, they stay cold a lot longer than a normal fridge/freezer basically meaning less noise.
@@just_noXi In a proper setup you can go much lower. You just need to speed up the cycle to move more heat and also reach lower temperatures.
Definitely loved this video and learned a few things from it.
Cold fusion happen when the induction on material inside the DC magnetic field make it cool down and fusion while heat is extract and transfer to the emf coil so just like get more energy than it put in because the heat generate more energy on the coil while extra cool down the material and increase it density
But you would stack them in series so that there is a temperature differential across each stage. A multiple stage device could easily use a 1 degree drop in temperature to convert mechanical motion into useful cooling. With enough insulation in theory, you could have a gravity powered freezer, a bit like a GravityLight :)
Here in Canada and I guess the US it's faster to boil water in a pot on the stove vs. the kettle. The kettle is 1500 watts, it's alright but not nearly as much as the stove top, now I know why
Finally we can see the knowledge from a statistical mechanics course put into practise
I can't wait till we have refrigeration systems based on this.
We probably won't, since they would be more expensive to produce compared to a fridge that just has a compressor, a few tubes and some liquid. It might become some sort of a niche application, but I can't see it replacing traditional refrigeration any time soon.
Love your videos. Relaxing and interesting. Thanks!
Should have used the induction cooker's wattage setting closest to the resistance cooker.
Excellent!
Very nice. Thanks for explaining
Awesome! I can't wait for this video!
I wonder...if you were to mount the Cado-whathisname in the end of one of them springs they use behind doors to stop them opening too far...then mounted it between 2 magnets then pinged the spring, would the cooling effect be greater? 🤔
Where's the induction cougar? 😂
I love these experiments with magnets! A few thoughts: Wouldn't a fridge, based on the magnetocaloric effect, slowly lose is cooling ability? The change of the magnetic domains takes energy and I suppose it comes from the magnet inducing the magnetic field. So, wouldn't a magnet after let's say 2 million cicles slowly lose it's magnetisation?
Another way to get water hot faster than just on a regular stove is to use an electric kettle. They have even less mass to heat up.
I'm still not sure which one is faster, kettle and induction or induction only.
Hvala!
Aren't induction stove tops already quite common? At least where I live they seem to be the most common type.
You should also put a gas stove in the comparison.
Very interesting video !
Since the external magnetic field rotates elementary spins in the gadolinium, wouldn't that be work done onto the system and thus contribute to the heating in addition to the lattice properties?
Would using induction to heat a home be more efficient than using electric resistive instead ??? Thanks
I really want to get one of those induction heater hotplates. They are really -cool- hot.
They are not expensive. Get one with plenty of power though. At least 2kW if you can (Or 1,5kW in the US I guess?).
How do these compare to a submerged resistive heating element?
Woah. 3 Categories during intro!
Thanks for nice video. I wish you good luck.
Pronounciation of archaic is archake
Du gør det sku godt :) skønne videoer du laver!
have you considered the temp sensor has a small current through it that the large magnet changes it and result in a change in temp reading?
What if you put the gadolinium on a swing over the magnet?!?
Hey! I wonder if this is how my electric tea kettle is boiling my water? Is it using magnets? It’s super fast! I even use it to boil water before adding it to the stove so it will boil faster.
Does it save money to get a magnetic stove instead of a resistance stove?
interesting video.
My physics professor brought in an induction cooker and attempted to explain how it cooks so much more quickly than a conventional or gas cooker. It didn't, because they don't.
A pound of chicken has about five times the heat capacity of a pound of aluminum. And, it's loaded with water that at 100 C will become the primary energy sink in the system. It doesn't matter if you're heating the pan with nuclear fusion.
how MUCH faster, brainiac
Still my 1600W Resistive Kettle cook faster than my induction 2000W
You should test it with already heated plate. If you wanna cook long resistive should be more efficient bcs its changing all power into heat without apparent power
Would be nice to see a Type K thermometer on the Magnet. 🧲 🌡️
To be fair, the conventional cooker you were using seems to be a fairly weak represantative of it's kind. Undoubtedly the first step in heating up itself is inherent with conventional cookers, but with a decent quality brand device the advantage in speed would be not as huge as to be seen in your test.
could you make the metal in to a wire and run in a loop go8ng through a bath of coolant
Nice
TH-cam NOTIFS!!! When Braniac uploads a video PUT SOMETHING IN MY NOTIFS!!!
It would be interesting to see how a natural quartz crystal responds in the field.
i have 120 volts to work with. i live in Canada
How to boil water without electricity?
I may attempt induction cooking with permanent magnets. It should be possible with a hand crank spinning magnets arranged with switching polarities. It may be a lot of work to operate though - heating me more than the cookware :) Thanks for watching!
Fire
How did nobody reply "fire" yet? xD
Me with a gas stove: Easily
Your welcome
Where can i get an induction cooker?
Where did you get those nice samples in the metal tin?
This tech is how some of the cryostats work to get the temperature under 4k. I think they use a magenetic salt of some sort.
Kinda stupid example with the cookers..the resistive one draws less power so more time for power to dissipate to the environment..try it with the resistive type of cooker that drops into the water directly and there you will see who wins ;)
I love his voice
Heating bacon and cooling beer: Magnets!
this guy has 3 phase 400v in his kitchen? or is that normal for whatever country this is?
thats commercial aircraft levels of power.
Beer and bacon. Two of the best things in life!
You forgot to compare heating it with fire. My parents always says gas is more efficient and cheaper than electricity.
Time of how fast the gas boils the water, and the cost of gas converted to the electrical equivalent.
I'm curious as well.
A little bit of research shows that gas is almost half as fast as induction. No idea on price tho.
Cougar??? ohhhh COOKER!
Neat
Add some of thermal paste
Stupid idea: Put the monster magnet in the freezer and see how much power it will gain, or do anything else to cool it down
Brainiac have a TH-camr spanish (timon se a vuelto loco)he copy your vídeo and have more 1.000.000 suscribe
What about a gas cooker?
All the refrigerators use motors to power compressor, so you are already using magnetic induction to cool stuff🍨
Higher voltage will not make them boil water faster sorry to correct you, it will just consume less amps. The power the appliance need its same. Less voltage more amps and vice versa.
12 volts at 1,000 amps is going to heat slower than 120 volts at 100 amps? I don't think so. They have the same wattage.
dont let the fire kill u
This has to be as close to “free energy” as we’re going to get.
It's still far from stealing energy from your neighborhood...
The input of energy in the system comes from the movement of the magnets. You still have to spend energy to move the magnets somehow.
@@gl1500ctv there is no movement of the magnets, the atoms are being rearranged against the lattice structure which causes heat just like bending an object causes it to heat up. the energy is being transferred from the magnet's atoms as it gets demagnetised
How Much Faster
compare it with gas
Your regular electric heater is slower than the ones without the rubber and just the coil.
"How faster..." should be "How MUCH faster..", or "How fast...".
Does this mean that magnets are cooking us?
Очень интересный эффект, но какого чёрта у автора всего 200 В в сети.
Looked like 225ml. I work as a chem lab aid.
Electric resistive cookers are rubbish, for sure. Show to heat up and slow to cook down. My house had an inductive cooker when I moved in, but I still prefer a gas cooker.
1c is NOT 1.8 f
Add natural gas please to the comparison! Answer in us dollars please?
69 views...nice!
bro i never got a notification wha t tehef cuk
Pure luck, if you were here so fast without a notification x) Thanks for watching!
Is magnets ( black magnets) good for health ???
I came here to find out: How faster?
In English, 1000W against 2000W, and it is not Rubbish ur Water Heater works the same, and it is far more superior. The Induction Heater has Hundreds of parts like complicated circuits AC/DC converter Mosfets LCD Displays flimsy push Buttons. The other instead has only 2 the Resistive Heater Potted in Waterprotected Cement, an analog Bimetal Heat sensing switch, and that is it. It even would work when it's in an Apokalypse, as long as the voltage is high enough it makes heat, u can connect directly a high voltage Solar cell without any regulator AC or DC, the other thing is just Elektronik waste that's stops working after 2 Years
