How many temperature magnets will degaussing?
Demagnetization temperature of magnet: Curie point is 750 DEG C and 760 centigradeGeneral gas stove flame center temperature up to 1000 degrees Celsius, degaussing is no problem! However, it should be noted that lighters generally do not fire more than 400 degrees Celsius, can not be erased.
For all magnetic materials, they are not magnetic at any temperature. Generally, a magnetic material has a critical temperature Tc, at which the arrangement of atomic magnetic moments is disordered due to the intense thermal motion of atoms at high temperatures. Below this temperature, the magnetic moment of the atom is arranged in order, producing spontaneous magnetization, and the object becomes ferromagnetic.
Curie temperature is the temperature at which material can change between a ferromagnet and a magnet. Below the Curie temperature, the substance becomes ferromagnetic, when the magnetic field associated with the material is difficult to change. When the temperature is higher than the Curie temperature, the material becomes a paramagnetic material, and the magnetic field of the magnet changes easily with the change of the surrounding magnetic field. The magnetic susceptibility is about 10 minus 6 times.
