The material and size of the magnet will affect the strength of the magnet. But how to measure the strength of a magnet? by yourself?
Below is two way to determine the magnet strength:
1. Gauss meter to measure
Placing the Gaussmeter directly on the surface of the magnet will display the measurement results
2. The same size of the magnet, can be judged by the weight of the iron block to be absorbed. The heavier the absorption, the higher the performance.
