How To Distinguish The Magnetic Force Of A Magnet

Magnets are a common thing in life, but do you know how to tell the size of an equivalent magnet?

The first method, put two of the same size of the size of the magnet can be adsorbed on the plane, such as: patch, blade, iron door, etc., with the hand to identify the size of the magnetic force. It’s always the right touch. No matter what you’re doing with it, feel is a very important feeling. The second method USES the electronic scale: the magnetic force is weak magnet and its density generally has a relationship, the magnetic force is relatively small if the density is small, the magnetic force is relatively large if the weight is heavy, the magnetic force is relatively small if the weight is light. In other words, heavier magnets are larger, and when measuring magnets, you need to be accurate to the gram.

The third kind of gauss meter, this kind of test results are more intuitive, but when the test need to pay attention to, the center of the magnet is measured the center of the magnet, if a measure of the edge of the magnet, a measure of the center of the magnet location is not accurate. Distinguish Magnetic Force

The magnetic force of a magnet is usually measured by a gaussian machine. Other test methods are as follows:

1. Helmhertz covibration coil test, which can test the whole magnetic flux of the whole 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 inside the magnetic field exhibits hall effect under the magnetic field;

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

4. Fixed suction test;

5. High-resolution tests can detect magnetic field changes of 1/100,000.
