What are the functions of metal soft magnetic cores, and what are the functions of metal soft magnetic cores in electronic circuits？

The metal soft magnetic core has many functions in the circuit, such as filtering, energy storage, oscillation and so on. Among them, many people do not understand the energy storage function of the metal soft magnetic core.

Energy storage is one of the important functions of metal soft magnetic cores. When the metal soft magnetic core is working in the circuit, the current flows through the enameled wire of the metal magnetic core inductance, and a magnetic field is generated around the enameled wire. Due to the magnetic field, the magnetic core will gradually become magnetized and store magnetic energy. So as to play a role of energy storage.

And what is the energy storage of metal soft magnetic core inductors? When the circuit is suddenly short-circuited, the magnetic core will release the previously stored magnetic energy. When the magnetic energy passes through the enameled wire, according to the principle of Faraday magnetism, current will be released, and the magnetic energy will gradually decrease until the magnetic core inductance is no longer discharged. The energy storage function of the metal soft magnetic core inductor can better protect the components in the circuit.
