Permanent magnets can be in our lives how to use

　　permanent magnets in the absence of an external magnetic field by definition is interference that can guarantee their permanent magnetic objects , permanent magnets does not refer to a single metal , is a general term with a permanent magnetic metal , ancient Sinan is a use of permanent magnets , that is the earliest use of permanent magnets in modern life can be how to use it .

　　permanent magnets having a strong magnetic field itself , so that it can be applied in the audio field , the magnet for high acoustic requirements play a good effect can improve the magnet , and the permanent magnets of the magnetic field itself meet acoustic requirements of the magnet , you can use it to create some high-end audio , allowing to optimize the sound quality .

　　permanent magnets can also use the jammers , and we all know that the demand for high -tech products of modern signal , using permanent magnets produced by diffusion magnetic jammers to block acceptance of technology products and divergence signal , so that to achieve the role of interference and ordinary jammer is different, there is no point in the case of permanent magnets made ​​using jammers can still play a role , this is unmatched by ordinary jammers .
