Abstract
The present invention relates to a magnetic core using a different type of magnetic material. The magnetic core according to one embodiment may comprise: a ferrite powder comprising manganese (Mn), zinc, iron, and oxygen (O); and a metal alloy powder made of at least two substances from among nickel (Ni), iron (Fe), aluminum (Al), molybdenum (Mo), and silicon (Si). Here, the magnetic core can comprise 67 to 72 wt % of the ferrite powder and 28 to 33 wt % of the metal alloy powder.
