Description of the characteristics of DC electromagnet

Characteristics of direct current electromagnet

1. Characteristics:

As the name suggests, the coil of the DC electromagnet is DC. The magnetic flux is a constant flux that does not change with time. There is no eddy current and hysteresis loss in the iron core. The core material can be made with a whole piece of steel or pure iron. Because of the convenient processing, the core of the coil part is usually made into a cylindrical form.

Two. Use of voltage:

The use voltage of DC electromagnet varies from 3V to 110V, and 12V and 24V are common.
