Abstract

This application describes a coil. The coil includes an output terminal, an input terminal, and a wire-winding part that is connected between the output terminal and the input terminal. A slot is disposed on at least a part of the wire-winding part, and a depth of the slot in any direction of a cross section of the wire-winding part is less than or equal to a distance between two points that are the farthest away from each other on the cross section of the wire-winding part. The wire-winding part is a metal conductor made through spiral winding. The input terminal and the output terminal are configured to connect the wire-winding part to an external circuit.
