Fun With an Induction Cooktop?
fishfrys writes "Besides generating heat quickly and efficiently in ferromagnetic pans, what sorts of fun things can you do with an induction cooktop? This seems like a pretty serious piece of electromagnetic equipment — boiling water can't be the only thing it's good for. I went to YouTube, expecting to find all sorts of crazy videos of unsafe induction cooktop shenanigans, but found only cooking. What sort of exciting, if not stupid, physics experiments can be performed with one? Hard drive scrubber? DIY Tesla coil? There's got to be something."
so fast they explode?
Now you can cook chicken with a Tesla Coil! The possibilities are end... well, you're still only cooking things with a tesla coil. Maybe you'll become a master at it and keep the chicken from being horribly burned in the wrong places, or not cooked at all in others. You could be the first man to be arrested for aggressive chicken handling!
There is no -1 Disagree.
that's what i have found so far. normally you cannot use aluminum on an induction cooktop, probably because a thick layer of aluminum is equally as conductive as the copper inductor in the cooktop, however a thin layer of aluminum can be brought to hover itself away from the cooktop and / or begin to glow if held in place. my cooktop took no damage from trying this but of course - don't try this at home

The baby's fine -- please stop sending business cards.
I remember seeing induction heating used to make a block of ice glow red hot.

Apparently it heats the trace amounts iron inside the ice so this only works with tap water. Not really sure if it would work with an iduction stove top though. Worth a try.
safer than your hand. modern induction ranges have safety mechanisms to prevent accidentally burning your hands or other non-cooking inductable materials, so you are probably limited to what will be perceived (by the range) as a skillet/pan/pot - large, ferrous surface.
Hardware modding may be required. Remove ceiling or wall before use. If you try it, on your own head be it - I do not guarantee your safety.
It's been carefully designed to be only usable in heating up pans and pots and maybe their contents. Maybe because a friend of mine got one that's so sentive that it sometimes decides his cooking isn't worth heating up!
Try cutting a large metal "washer" out and placing it on the "burner." This may demonstrate Lenz's second law and cause some violent repulsion . . . although I haven't tried it.
I do know it doesn't work with my gas burners though.
Try some unexploded WW2 shells, some walmart bullets, a kid with braces. An arm with a tattoo. A hamster that ingested iron shavings. You were looking for unsafe and stupid things to try, right?
It's a nerd site. We like to investigate, determine, build and generally fiddle.
The real question is "Why is a boring muggle like you even doing here?"

Its not hard to convert one to a MASER that can boil water, burn wood, or blow up zombie heads at 50 yards or more. Not that Ive tried it of course, that would be dangerous, irresponsible, and possibly illegal. Just sayin'

Perhaps we should get off your lawn and stop tinkering with this "science" garbage, too? Your name isn't Red Foreman, is it..?
Bite my shiny metal ass!
Sure there is, me and my brother managed to get pieces of metal red glowing.
We connected our own coil to stuff inside, and any metal object that we put in/on the could started glowing.
Last time I used my induction stove to cook water for noodles, I put the power to max, all the while listening to music on my iphone via headphones. You know, those standard apple headphones with microphone and volume controls. Right when I put the power to max, the music went off. Turns out the volume was set to minimum. So I tried to restore the volume via touch controls, but it went to minimum immediately, again. I already had experience with malfunctioning apple headphones (cable short-circuit) so I unplugged them, which helped. Then I noticed that the proximity to the cooktop had an effect. Apparently the induction pattern induced the same signal in the headphone cables that a volume down would produce...
Anybody with a Bosch induction stove and an iPhone/iPod should try to confirm this.
Feel free to fuck off any time.
Induction cooktops operate at a frequency of a few tens of kilohertz. Using it to excite a Tesla coil probably can't be made to work, at least, not with a reasonable number of turns on your secondary coil. The coil under the surface of the cooktop has a large number of turns.
(To step up voltage, you want a few turns on the primary, and many times as many turns on the secondary.)
You can cook food with one. End of story.
Why are all of these pointless, irrelevant questions asked? This site is now worse than Yahoo Answers at the exception of the lame cartoon avatars. Get a job, and get to work. You might find yourself doing something productive.

Neat. I imagine their are potential lithography applications. Or you could just inject a BB into an egg and cook it from the inside out for the ultimate in runny whites.
Someone had to do it.

I've seen induction heating used to temper truck axles, among other things. Though I imagine that with minor tweaks you could make one hell of a HERF weapon out of one. Screw up all the cell towers within a few miles, etc. Check ebay for used resturaunt equipment.

2 things:
1) Asking is how you find a place to start. When I want to create with electronics, I don't do mine copper.
2) Presuming you meant Linus, he asked several people about how to create a kernel. He was taught a foundation of computer science.
Do you think Linus that created a kernel with no knowledge? having never asked an computer science questions?
The Kruger Dunning explains most post on
Would that work?
'Imagine if Linux[sic] would have asked Tanenbaum on how to make a good kernel.'
We might have got a good kernel.

Great minds think alike; fools seldom differ.

Here is one experiment to try, how much can I fool around with an induction cooktop before I hurt myself?

There is a triangular piece of metal in the ice. It's a demonstration by Huettinger, a manufacturer of induction heaters.

I think water would flash to steam before you got it to glow. Unless it was under enormous pressure I suppose.

Why are induction cooktops so expensive (here in NY)? I understand they're sold cheap in Asia. They don't seem to need to be very expensive.
If they were cheap, they'd be worth using for energy efficiency. But they cost more than the energy savings.

Passports with IC chips in them can have the chips fried by a microwave oven, but it's hard to figure out how much to fry them without burning the passport itself.
Can induction cooktops do it more precisely?

No offense, but if the ice were this hot, it'd melt and flash into steam. There's probably metal (not just trace amounts) embedded in the ice and that's what's glowing.
rig up a matching coil so that the magnetic field can be converted back to electricity and charge a battery powered device.

"Do you think Linus that created a kernel with no knowledge? having never asked an computer science questions?"
That's certainly what Professor Tanenbaum thought.
If I had an induction cooktop, I'd not play around with it, because these are expensive and you never know what will damage the thing. They likely use some form of feedback, and doing stupid things could cause the driver to do something bad and kill some parts. Doesn't seem worth the risk. Maybe someone familiar with the drivers can comment on how robust they are.

With no you-tube videos, and not even any Slashdot replies interesting enough to get enough mod points to be seen (and that is saying a lot), it appears that there is nothing fun that you can do with whatever it is that you are asking.
No, he didn't.
Seeing that the supply/load is INDUCTIVE, look at the plate being the PRIMARY COIL of a transformer, you only need to supply a SECONDARY COIL. Play with some transformers and a voltmeter. You may find you can charge your phone without having some fancy jack-plug for it's transformer, or maybe you can charge the ipod whilst listening AND cooking at the same time!

If you want to play around with induction heating but don't want to risk an expensive cooktop, there is a slick little open source heater here http://www.neon-john.com/Induction/Roy/Roy.htm. About the same power as a residential cooktop but without all those pesky protections and a lot cheaper to build. A company called http://www.fluxeon.com has kits and stuff for this project.
