Types of Coils for Surface Heating

There are generally four types of induction heating coils for surface heating.  They are:

1. Inductor with central rod
2. Hairpin
3. Single-turn cylindrical
4. Multi-turn cylindrical

It should be noted as well that a magnetic flux controller will greatly improve induction heating coil performance.  That magnetic flux controller should contain a core and poles for optimum design.  These items are just part of creating an optimal design to achieve peak performance.
