The effect of temperature on magnetic material?
If the temperature is high, the magnetism of the magnet will be weakened. If it continues to rise, the magnetism of the magnet will become weaker and weaker, and eventually the magnetism will disappear forever!
High temperature, weak magnetic
Temperature coefficient (1/K)When the temperature coefficient changes in temperature and range, the relative change of the relative permeability of each variable 1K:The permeability at which the temperature is constant is the permeability at which the temperature is constantCurie temperature Tc (DEG C)At this temperature, the material is ferromagnetic (or ferrimagnetic) and becomes paramagnetic.
