Abstract
A magnetic core is made of a composite magnetic material having a relative permeability of between 1 and 29 at a frequency range from 20 kHz to 2.5 MHz. The composite magnetic material consists of cobalt and nickel particles having an average diameter in the range of 1 to 100 micrometers, and a polymer base binding the particles to form a core.
