Calculating the Resistance in an Induction Heater
I am trying to build a 200A induction heater and have the understanding that it is basically an inverter in series with a transformer. The following is a very basic schematic of my circuit:
simulate ...

Eddy current levitating force?
Suppose the RMS value of AC sinewave current current in the coil/solenoid is kept constant,
but the frequency is increasing.
(Might be done perhaps by adjusting the Input Voltage)
What will happen ...

Inductive kickback requires a capacitor to "kick back"?
I recently watched a video where a person demonstrated the spark caused by inductive kickback. He also ran a simulation of it in Falstad.
What confuses me is the capacitor and resistor, which he says ...

Mosfet gets destroyed in induction heater
I am making an induction heater. MOSFETs IRFZ44N, C = 0.1 µF, R1=R2=220 Ω, L1=L2 (don’t know I made it by myself but it’s greater than the induction coil. I made it using 24 AWG wire, 30 turns around ...

How does a changing electric field in the secondary wire of a transformer produce a potential difference?
I want to first give a quick rundown to make sure my core concepts are correct.
All charges produce an electric field (and to a degree a magnetic field in the form of a magnetic moment due to the ...

Would a voltage appear across the switch?
This is a situation of a de-energizing transient. My question is, would a voltage appear across the switch even in the presence of the discharge resistor \$R_{2}\$?
I am asking this because, I wanna ...

Can a power cord running through a metal fitting induce voltage?
When I dug out an old floor lamp, I decided to run some basic "safety" checks using a multimeter. To my surprise I measured some voltage on the lamp post and I believe that this voltage is ...
