A method of forming a consolidated component having a complex shape includes providing a first component having a first shape similar to the complex shape. The method further includes placing the first component in a chamber and surrounding the first component with a medium. The method further includes applying pressure and at least one of heat or electricity into the chamber to process the first component to form a consolidated component having the complex shape.

A magnetic material is formed of an aggregate of magnetic particles. When a magnetic particle is rotated by 360/n degrees (n is an any integer equal to or greater than 6) around a gravity center position of the magnetic particle in a planar region, an area of the magnetic particle after the rotation overlaps with an area of the magnetic particle before the rotation by 90% or more. In the planar region, gravity center positions of from nine to eleven magnetic particles are on a band portion in a rectangular shape. For the magnetic 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 0.6α, and a 90% cumulative frequency distribution is equal to or less than 1.4α.
