How to detect magnets
Every product needs to be checked whether it meets the design standards during the production process. Magnets are no exception.
First of all, in terms of surface treatment, we need to use a film thickness gauge to test the thickness of the electroplating layer of the magnet, so as to achieve the best quality of electroplating during the electroplating process.
The second is the size of the specification. In this process, we need to use a micrometer and a vernier caliper to control the tolerance within the specified range. Usually the tolerance of the magnet is plus or minus 0.05mm, of course, some customers have stricter requirements for it.
Next is the magnetic test. The magnitude of the magnetic force can be measured by a Gaussmeter and a Fluxmeter. The Gauss meter is mainly a measurement of the magnetic force on the surface of the finished magnet. The fluxmeter is more standardized than the Gaussmeter. The fluxmeter measures the magnetic flux of the magnetic field of the magnet on the surface area.
