Abstract: A magnetic element includes a first magnetic core, a coil and a second magnetic core. The first magnetic core is made of a ferrite material, and a magnetic permeability of the first magnetic core is higher than 700. The coil is installed on the first magnetic core. The second magnetic core is formed by molding an alloy composition. In addition, the coil and at least a portion of the first magnetic core are covered by the second magnetic core.
