Its known commonly that iron, nickel, and cobalt are magnetic, but it isn't known commonly that these are just the only FERROmagnetic metals. All metals have some magnetic properties. Copper and aluminum are diamagnetic, meaning that they create a field of their own when exposed to a field. Try dropping a small magnet down a copper pipe. This will demonstrate its diamagnetism, as the magnet takes longer to fall than you would suspect, due to the opposing force created by the pipe.
This property of magnetic opposition is used to construct induction heaters, and many other electronic components. When a magnetic field that switches between positive and negative very quickly is put into a chunk of diamagnetic metal, the electrons in the diamagnetic metal must move back and forth so quickly that they heat up from the friction and cause the metal chunk to melt. Basically, the magnetic field is picking the metal up and shaking it, atom by atom, very very quickly.
@fercarcas i think the loop is only to allow the copper tubing to run back in the opposite direction, enabling the two opposite magnetic fields that produces induction.
@TJDeadkid finding from several people that do this, you can find between 15% to 30% of copper cents just in circulated coin. Some people order the coin in $25.00 boxes of 50 rolls from their local bank/credit union. I order $4,000.00 pallets of $50 bags (80 Bags) and go through those. I average around 22% from what I sort through.
100% props on the cool induction heater. I've been researching about it for the last year or so. Don't take any offense, since I'm just a very blunt guy, but despite the coolness of what you can do, you really suck at videotaping. Really. Can you put more effort into that? It isn't rocket science.
@TheDhiguy a current passed through ANY conductor creates a magnetic field, a magnetic field passed through ANY conductor creates current. Current is produced and produces heat of course.
@savorfan The coil has an alternating current running through it, so the copper inside the coil is experiencing an alternating magnetic field. This alternating field induces what are called Eddy currents in the copper. The Eddy currents are induced in a way that they create a magnetic field in opposition to the magnetic field produced by the coils. These opposing magnetic fields are what cause the repulsive effect. I suspect that the force is upwards because the coils get wider as it rises?

I thought that induction heating woks only on magnetic element ( iron , cobalt, nickle) , how does induction heating work on aluminum and copper ??
I will be thankful for your help

I wrote an iPhone app, Thermal Light, that lets you measure the metal's temperature from 1000F-2700F!

hello, nice video. One question, why is necessary the single loop in copper pipe? Is there any electromagnetic property associated with?

Are you interested in large amounts of pre 1982 95% copper pennies? I can produce 1 to 3 tons a month. Let me know.

copper is non magnetic then how it melts without iron crucible?
