How high can the magnetic force of the magnet be charged?
At present, the magnetic force on the surface of magnet is mainly based on the magnetic flux density, in Gauss or Tesla.
And this value (surface Gauss value) depends on the material and thickness. In terms of thickness magnetization, the thicker the thickness, the higher the magnetic force.
Taking the strongest Nd-Fe-B magnet with thickness of 50 mm and the highest grade N52 as an example, the surface magnetic force can reach 7000 ± 10% Gauss.
However, the magnetic force of super magnetic tools made of special arrangement can reach 15000 ~ 20000 Gauss.
(such products can refer to super magnetic rod and super magnetic disk)
Because Gauss / Tesla is a unit of density, it refers to the magnetic force per unit area. It can be simply thought of as a single point magnetic force.
Therefore, we need to investigate the area according to the design in order to be more accurate.
