Abstract
A magnetic composition includes first, second, and third magnetic metal particles. The first magnetic metal particles have an average particle size of 10 μm to 28 μm; the second magnetic metal particles have an average particle size of 1 μm to 4.5 μm; and the third magnetic metal particles include insulating layers disposed on surfaces thereof and have a particle size of 300 nm or less. Therefore, eddy current loss of an inductor having a body formed of the magnetic composition may be improved, and high efficiency and inductance of the inductor may be secured.
