Magnetic core

Technical Field

The utility model relates to the technical field of inductors, in particular to a magnetic core.

Background

An inductor, also known as a choke, a reactor or a dynamic reactor, is a component that converts electrical energy into magnetic energy for storage. The inductor has an inductance that only impedes the change in current. If the inductor is in a state of no current passing, the inductor tries to block the current from flowing through the inductor when a circuit is switched on, and if the inductor is in a state of current passing, the inductor tries to keep the current unchanged when the circuit is switched off.
