How to calculate the distance between the coil and workpiece?

The shorter the distance, the more efficient the process will be.

The shorter the distance, the more efficient the process will be. If you can have a gap of ten thousands of an inch, you will heat the parts very, very efficiently. It’s not practical in many environments to have that type of a tolerance though. So the question is what tolerance do you have to maintain in your process and optimize accordingly.
