    But you don't need to insert the pot into the coil for the induction cooker. Is that done with a stronger magnetic field?

    couldn't you hook something like this up to a simple mains voltage to dc converter to draw more watts thus more heating potential? Or would it better to use a larger coil?

    Hi, i was tried, when i increasing the Voltage form 0-3 v one MOSFET was getting over heat, at the same time it is drawing more than 3.5A @ 3.5V range, can you please let me know the reason.
    Please help me to resolve the issue

    Howz those metal getting hotter ? Is that because of semi conductors electron flow with resistance it self ?

    Hey, i just tried to build a circuit following the schematic of your circuit but i always get a type of short circuit... Im not getting my powersupply to get out of the current limitation mode which suggests a short circuit. Do you have any idea where this could come from? I double checked the mosfets for pin errors etc but the circuit itself seems to be exactly the one you showed in the video. Thanks in advance!

    Non professional don't understand this experiment it is related to electrical engineering ' hub of knowledge. When current is pass in the turns of a coil that produces magnetic flux likes with itself is known as self inductance or solenoid. The magneting force cut air which is to be equal to absolute permeability multiplied by magnetic field.

    the one thing which bugs me about this circuit are the 2 inductors (here: 100µH) at both sides of the main coil. Why are they needed?

    Is it possible? If you increase amps/current to extreme degree and create enormous magnetic pressure at the center of induction coil, and then put a piece of pure carbon in it. Will the enormous magnetic pressure result in carbon turning into a diamond?

    With an inductor in an ac circuit wouldn't that cause the pharaoh magnetic rod in the middle of it cause it to to heat up?

    I usually avoid videos like this , but I figure this can't be one where things are heated, and just a lot if playing around, like the videos where they build fly backs, and make arcs the whole video, but this is much better, great video Mr Scott!!!
