How to separate two powerful magnets together?

For all of the magnetic material, not at any temperature are magnetic. Generally, magnetic material has a critical temperature Tc, above this temperature, the magnet due to the intense thermal motion of atoms under high temperature, the arrangement of atomic magnetic moment is chaotic. Under this temperature, the atomic magnetic moment order, produce spontaneous magnetization, become ferromagnetic objects. Using this feature, people developed a lot of control components. We use electric rice cooker, for example, using the characteristics of the magnetic material of the Curie point. Central in the bottom of the rice cooker with a magnet and a Curie temperature is 105 degrees of magnetic materials. When the pot of water dry food's temperature to rise from 100 degrees. When the temperature reaches about 105 degrees, because the strong magnet to absorb the magnetic materials magnetic disappear, the magnet will lose suction in it, then spring between magnets and magnetic materials will take them apart, drive the power switch is disconnected at the same time, stop heating. Curie temperature refers to the material can change of temperature between the ferromagnetic and magnet. Below the Curie temperature when the material become a ferromagnet, at this time and materials related to magnetic field is very difficult to change. When the temperature is higher than Curie temperature, the material became paramagnetic, magnets, magnetic field, it's easy to change with the change of the magnetic field around. At this time of the magnetic sensitivity of about 10 to the negative power 6. When two powerful magnets together can be heated to a temperature of about two hundred degrees Celsius temperature, under the temperature of magnet magnetic greatly abate, magnet attraction between decreased.
