The design of an electromagnetic coil typically starts with a characterization of the magnetic field needed for the application and the shape and dimensions of the coil.

Standard coils are available for insulation classes E, F and H. The insulation class determines the coil’s maximum operating temperature for a specific life: The temperature rise of continuously …

I’ll tell you how you can produce similar inductors, make coil forms that easily release a tightly wound coil after wrapping and how to wind the coils with uniform turn spacing.

There are several equations that can be used in conjunction with the Colmac "CoilPRO" selection software program to speed the process of sizing coils. Following is a listing of several of these …

A conveyor or channel coil, for example, can be looked at as a rectangular coil whose ends are bent to form “bridges” in order to permit parts to pass through on a continuous basis.

Cooling Coil Processes A cooling coil both cools (sensible) and dehumidifies (latent) an air stream.

-The energy in an inductor is stored in the magnetic field within the coil, just as the energy of a capacitor is stored in the electric field between its plates.
