What are the advantages of magnetic materials in RAM?

Answer:

When the frequency increases, the magnetic conductivity of the material will be reduced, and the magnetic properties of the magnetic material are influenced by many factors. Generally, the permeability and saturation magnetic induction of metallic magnetic materials decrease with the increase of temperature.
The magnetic properties of magnetic materials depend not only on their chemical composition, but the temperature and frequency are the most important, and the coercivity and loss increase.
(2) frequency. The change of frequency also has a certain influence on the magnetic properties, which can decrease the permeability of the material. The temperature has a remarkable influence on the magnetic properties of magnetic materials. The magnetic material will lose magnetism and become paramagnetic material. Internal stress occurs when machining metal magnetic materials. (1) temperature must be annealed. To eliminate stress, the core loss is increased. When the temperature exceeds a certain value, it is also related to the method of machining and the conditions of heat treatment. In addition, restore magnetism
