A magnetic element includes at least one first air gap. A first portion of the first air gap is arranged between the first projection line and the second projection line. A second portion of the first air gap is beyond the region between the third projection line and the fourth projection line. Due to the air gap, the dielectric constant between the first end part of the winding and the magnetic leg and the dielectric constant between the second end part of the winding and the magnetic leg are reduced. Moreover, the electric field distribution of the first end part and the second end part will be more uniform, and the partial discharge extinction voltage will be increased. The volume and the cost of the magnetic element are both reduced. In addition, the equalizing rings are not required. Consequently, the fabricating process of the magnetic element is simplified.

A refresh rate switching method and an electronic device are provided. In the method, the electronic device dynamically switches a corresponding screen refresh rate by determining whether a current display image is a high frame rate scenario or a standard frame rate scenario. In the high frame rate scenario, a relatively high screen refresh rate is used to support a high display frame rate. In this way, a user can obtain experience of the high display frame rate, and the display image is smooth without motion blur. In the standard frame rate scenario, a default low screen refresh rate is used to reduce power consumption of an entire system.
