Magnets are very common in daily life, but do you know how to distinguish magnets of the same standard size?
One method is to place two magnets of the same size on an adsorbable plane, such as stickers, blades, iron doors, etc., and use the sense of touch to distinguish the magnitude of the magnetic force. Regular perception is the correct way. No matter what you want to use them for, perception is a very important factor.
The second method is to use an electronic scale. The magnetic force of a magnet is usually related to its density. If the density is relatively small, the magnetic force will be relatively weak; if the component is heavier, the magnetic force will be relatively stronger; conversely, if the component is lighter, the magnetic force will be smaller. In other words, heavier magnets tend to have relatively stronger magnetic forces. When measuring magnets, the measurement should be accurate to grams.
The third method is to use a Gaussmeter. The results of this test are more intuitive and clear. However, it should be noted that during the testing process, the middle part of the magnet is usually measured. If the edge of the magnet is measured, the direction in the middle of the magnet may not meet the standard.
Generally, the magnetic force of magnets is measured by a Gaussmeter. Other testing methods include:
1.Helmholtz resonant coil test, which can test all the magnetic flux of the entire magnet;
2.Hall effect detection. The conventional detection method reflects the result in the form of Gauss values. Its principle is that the traveling wave tube exhibits the Hall effect under the action of a magnetic field;
3.Axial magnetic field description, which is used to describe the magnetic field dispersion of magnetic assemblies;
4.Fixed suction test;
5.High-resolution test that can measure magnetic field changes of up to 100,000.
