Induction Heating of an Iron block

I am looking for some help in setting up an induction heating simulation
I have constructed a 1/2" thick, piece of iron which is 4" tall by 6" long. I need to simulate the effects of induction heating on the block. In my real life experimental setup I have taken the coil out of an simple commercially available induction heater (made normally for cooking rice) and place it underneath the bottom of the iron piece which I heat up with the inductive heater. The magnet field through the coil is oscillating with a frequency of 60hz and I have been successful in heating up the chuck temperature to about 600C. However I need to get a better insight into how well the block is heated by the inductive heater.
So my problem is that I have so far been unable to setup a COMSOL simulation where I can induce an oscillating magnetic field that is perpendicular to the bottom of the iron chuck. I have been trying to use transient simulations where I define a function that emulates the 60hz sinusoidal behavior of the magnetic field. Any help would be useful such as how I can couple the induction to cause heating in the iron.

Hi
I believe you should use the harmonic sovler approach, look it up in the doc (and not the time resolved solver)

Good luck
