Hi
I'm trying to make my own small induction furnace. I've made a small coil, the same shape as a solenoid. I'm using the electronics of a small induction stove so that is all in working order.

For testing purposes, I'm using a round magnetic bar inserted into the middle of the coil. The coil is about 30cm long and the bar is about 1 meter long. The problem is, that when I stick the bar completely through the coil, so that the coil is in the middle of the bar, the bar doesn't get heated. But as soon as I stick the bar only halfway through the coil it gets very hot.
Can anyone explain to me why this is happening?
Thanks in advance :-)
