Why does a power inductor make a loud noise when first turned on then decay to a calmer "hum" later?
I'm puzzled by this phenomenon. According to my lacking knowledge, a huge current draw at startup is exclusive to electric motors, where the lack of back EMF at zero speed causes big current draw. So ...

Why doesn't an induction heater and an induction ring launcher produce the same effect?
I want to know why an induction heater and an induction ring launcher don't produce the same effect. Both seem to use AC voltage to power a solenoid(which induces a voltage in a pipe) so why doesn't ...

According to my understanding, this induction heater should be melted, but it's not. Why not?
I opened up this induction heater to find that it only has maybe 12 AWG wire in its work coil, rated for 30 A RMS. I've been doing induction heater simulations for a project, and the two topologies I'...
