Why does the magnet surface magnetism data measured by gauss meter change?

Recently, some netizens asked why the data of the permanent magnet measured by the Gauss meter will change? Next, Dongguan magnet manufacturer courage will tell you about this Gauss meter measuring instrument.

Gauss meter is used to test the surface magnetic field strength of magnetic materials. It has been proved by experiments that it can test soft and hard magnetic.

Why does the measurement data of the permanent magnet change?

We generally use a gauss meter to measure the gauss of the magnet surface. However, the Gauss values measured at different positions on the surface of the magnet are different, the magnetic force is different every time the position moves, and the data measured by different Gauss meters are also different, and the error is relatively large. Our company uses a Japanese Gauss meter. You can also buy it for a few hundred yuan cheaper domestically.

Usually, the magnetic force in the center (the center surface magnetic force) is weaker than the magnetic force at the edge of the magnet. Usually, the magnetic force of this magnet is the highest surface magnetic force (many Gauss meters now have a locking function, that is, the highest value is locked).

PS: the Gauss of the magnet surface is like this, which is inversely proportional to the area and directly proportional to the thickness.
