In terms of magnetic materials alone, strong magnetic magnet products will become non-magnetic after reaching a certain high temperature. Generally, magnetic materials have a maximum temperature value Tc. Above this temperature, strong magnets will move violently under high temperature conditions, and there is no order in the placement of atomic magnetic moments. Below this temperature, the atomic magnetic moments are placed neatly and regularly, spontaneous magnetization occurs, and the object becomes a magnetic iron material.
How strong is the magnetism of a powerful magnet? We used to do this: Pushing the magnet sideways means that the magnets are still attracted together, only moving in parallel, until they move away at a certain interval, the magnetic attraction will be greatly reduced. Small, at this time add more force to be able to separate.
When we buy strong magnet products, we all have a Curie temperature value, then this Curie temperature. Curie temperature refers to the temperature at which the material can be changed between ferromagnetic and paramagnetic. When the temperature is lower than the Curie temperature, the substance becomes ferromagnetic, and the magnetic field related to the data is difficult to change at this moment. When the temperature is higher than the Curie temperature, the substance becomes a paramagnetic body, and the magnetic field of the magnet is simply changed with the surrounding magnetic field.
Therefore, temperature is an important factor that affects strong magnet products. When we buy magnetic products, we must consider the surrounding environment you are in. This is also a reason that affects the demagnetization of strong magnets. Of course, the stronger the magnet is, the stronger the magnet is. It is difficult for us to separate when we are together. High temperature heating is still needed to destroy the electrons in the magnet to achieve the performance of magnetic weakening.
