Magnetic material and inductor

A magnetic material includes magnetic particles. When a magnetic particle is rotated by 360/n degrees (n is an any integer equal to or greater than 2) around a gravity center position of the particle in a planar region, an area of the particle after the rotation overlaps with an area of the particle...

Zusammenfassung:A magnetic material includes magnetic particles. When a magnetic particle is rotated by 360/n degrees (n is an any integer equal to or greater than 2) around a gravity center position of the particle in a planar region, an area of the particle after the rotation overlaps with an area of the particle before the rotation by 90% or more. In the planar region, gravity center positions of from nine to eleven particles are present on a band portion in a rectangular shape. For the particles in the planar region, when a number-based 50% cumulative frequency distribution of maximum lengths in a direction passing through respective gravity center positions is defined as α, a 10% cumulative frequency distribution is equal to or greater than 0.9α, and a 90% cumulative frequency distribution is equal to or less than 1.1α. A surface of the particle is covered with an insulating film.
