ABSTRACT:
Disclosed is a process for producing a magnetic core, comprising the first step of bringing magnetic powder of a metal into contact with a polymer dispersion, followed by drying, to form an insulating layer on the surface of the magnetic powder and the second step of compression molding the magnetic powder. Also, disclosed is a magnetic core produced by the above process.
A magnetic core according to this invention has, since good insulation between magnetic powder particles can be ensured with a small amount of an insulating material, high magnetic flux density, small core loss and excellent frequency characteristics of magnetic permeability and is particularly suitable for use in high frequency range of some 10 KHz or higher.
