Strong magnet body is a strong magnet among many magnetic materials, which has not been widely used in our lives. So be careful and pay attention when using it. Because the magnetism is relatively strong, it can absorb dozens or even hundreds of times the weight of small magnets. If used improperly, such a strong suction force can cause damage. And because the suction force is relatively large, when the iron piece is put in, it cannot be thrown from a long distance, and it must be put slowly at close range. Because the magnet is not iron, it is hinged iron boron rare earth sintered, very brittle, to be loaded slowly.
In addition, the installation must be operated by professionals and equipped with protective tools to avoid the huge damage caused by strong magnets. Some strong magnets require a protective cover due to their fragility, which can increase the service life of the strong magnet. So, don't forget about these aids when you need them.
Strong magnets are common in life, but do you know how to distinguish magnets of the same specification?
One method is to place two magnets of the same size and specification on an adsorpable plane, such as patches, blades, iron doors, etc. And use feeling to distinguish the magnitude of the magnetic force. It usually feels right. Whatever you want to do, feelings are important feelings. The second method is to use an electronic scale: magnets with weak magnetic force are generally related to their density. If the density is small, the magnetic force is relatively small. If the weight is large, the magnetic force is relatively large. On the contrary, it is light in weight and has little magnetic force. That is, when the heavier magnet is larger, it should reach grams.
The third type of Gaussian meter, the result of this test is more straightforward, but in the test, the magnet center measures the magnet center, and if the magnet edge is measured, the magnet center position is not accurate.
Magnetic tests are generally measured with a Gaussian machine. Other test methods are:
1. Helmholtz resonance coil test, which can test all the magnetic flux of the entire magnet;
2. Hall effect detection, the conventional detection method is reflected in the form of Gaussian value. The principle is that the wavetube in the magnetic field exhibits the Hall effect under the magnetic field;
3. Axial field description, used to describe the magnetic field distribution of magnetic combinations;
4. Fixed suction test;
5. The high-resolution test can measure the change of magnetic field by one part in 100,000.
