Abstract
A magnetic element is provided and includes a first magnetic core, a second magnetic core and two windings. The first magnetic core is made of a first material and includes two winding pillars and two connecting parts. The first magnetic core has a first permeability. The second magnetic core is made of a second material and has a second permeability. The first permeability is less than the second permeability. When the current flows through the two windings, a closed magnetic path is generated in the first magnetic core, the magnetic flux generated by the closed magnetic path flows through one of the winding pillars, one of the connecting parts, the other one of the winding pillars and the other one of the connecting parts in a direction, and the magnetic fluxes generated on the second magnetic core are cancelled out by each other.
