How To Distinguish The Magnetic Force Of Special-shaped Strong Magnets

1. Special-shaped strong magnets Put two magnets of the same size on a plane that can be adsorbed, such as: patches, blades, iron doors, etc., and use the feel to distinguish the size of the magnetic force. Often the feel is the correct feeling. No matter what you're going to do with it, feel is a very important feeling.

2. Use an electronic scale: A magnet with weak magnetic force is generally related to its density. If the density is small, the magnetic force is relatively small. If the weight is heavy, the magnetic force is relatively large. On the contrary, if the weight is light, the magnetic force is small. That is to say, the heavier magnets are larger, and when measuring the magnets, it must be accurate to the gram.

3. Gauss meter, the results of this test are more intuitive and clear, but when testing, it should be noted that the center of the magnet is measured by the center of the magnet.

The magnetic force of the test magnet is generally measured with a Gaussian machine. Other test methods are:

1. Helm-Hertz resonance coil test, which can test the entire magnetic flux of the entire magnet;

2. Hall effect detection, the conventional test method is reflected in the form of Gaussian value, the principle is that the traveling wave tube in the magnetic field exhibits the Hall effect under the magnetic field;

3. Axial field description, used to describe the magnetic field distribution of the magnetic combination;

4. Fixed suction test;

5. The high-resolution test can measure 1/100,000 magnetic field changes.
