Abstract
A method for making a magnetic material comprises mixing and homogeneously blending a magnetic crystal or several tens of metal oxides with a rubber powder material at a weight ratio of 1:10; shaping the mixture by compressing and heating the mixture using a compression shaping machine, in which the rubber material has the properties of flame resistance, impact resistance, high strength, high resistance, high sensitivity, etc. A compression shaping mold can be used to make the mixture into a product with a suitable shape or model and anti-EMI characteristics and suitable magnetic performance (permeability coefficient ratio adjustment 10 to 12000 mu i. Furthermore, an enclosure or component of an electric product (filter, inductor) can be made from the mixture so that each electric product can achieve an electromagnetic compatible (EMC) effect.
