For who don't know how does induction heating work, a short description can be found here.
However, my question is about physics. Assume I have a coil inductor calculated carefully 50 uH as below:
the inductors Diameter is 20 mm and length is 1.8 * 40 = 72 mm.
9.4 A AC current is applied to the inductor at 33 Khz.
Now that I know how my inductor works, assume I placed an iron stick (1 cm diameter and 20 cm length) into the center of the inductor as below:
How can I calculate the dissipated energy as heat on the iron stick? How can I calculate in how much time this system can heat the iron stick up to 500° celsius?
What kinds of calculations are involved here? Could you explain them step by step?
this is schematic:
This is the power graph of the coil inductor:
