[0002] Generally speaking, the energy storage of an inductor is proportional to its inductance. In some areas where inductors are used, it is necessary to increase the inductance at lighter loads (i.e., low currents) without increasing the volume of the inductor or reducing the inductance at heavy loads (i.e., high currents), thereby improving the volume utilization of the inductor.

[0003] When the inductor core is in use, it needs to generate an electromotive force by changing the current passing through it, thereby resisting the change in current. The current of the current cannot be adjusted according to the needs of the user, resulting in the user being unable to adjust the electromotive force generated by the inductor core according to their own needs, and the practicality is poor.
