To measure the magnetic strength of a NdFeB magnet, the most common method is to use a Gauss meter (also called a magnetometer). Place the sensor probe of the Gauss meter close to the surface of the magnet—ideally at the center of one pole.
How to measure the magnetic strength of a NdFeB magnet?
To measure the magnetic strength of a NdFeB magnet, the most common method is to use a Gauss meter (also called a magnetometer). Place the sensor probe of the Gauss meter close to the surface of the magnet—ideally at the center of one pole. The device will display the magnetic field strength in units of Gauss or Tesla. This method gives a quick and accurate reading of the surface magnetic flux density, which is useful for comparing magnets or checking quality. If you don’t have a Gauss meter, some people use simple pull tests with a force gauge to measure how much weight the magnet can hold, but this is less precise. For most business and engineering needs, a Gauss meter is the recommended tool.
