Claim 0:
1. A coil, comprising:
an output terminal;
an input terminal; and
a wire-winding part that is connected between the output terminal and the input terminal,
wherein a slot is disposed on at least a part of the wire-winding part, the slot is disposed between outer edges of a width of the wire winding part at the at least a portion of the wire winding at which the slot is disposed, and a depth of the slot of the wire-winding part is less than or equal to the width of the wire-winding part, to reduce an eddy current loss caused in the coil by a magnetic field, wherein the slot comprises at least two portions, wherein a first portion of the slot cuts through the wire-winding part of the coil, and wherein a second portion of the slot has a preset depth disposed on the second portion of the wire-winding part of the coil, the preset depth less than a depth of the wire-winding part,
wherein the wire-winding part is a metal conductor made through spiral winding,
wherein the input terminal and the output terminal are configured to connect the wire-winding part to an external circuit.
