Strong magnets belong to the powder metallurgy category with high surface activity. Special attention should be paid during phosphating to avoid damaging the surface characteristics of strong magnets, otherwise the surface of the electroplated product will not be flat and smooth. The relevant formulas for electroplating hardware and electroplating magnets are different, but the electroplating process and equipment of magnet companies are the same. Magnet factories should pay special attention when selecting electroplating suppliers. The chamfer before electroplating should be done at a reasonable angle, as too small an angle is not easy to plate, and too large an angle can cause the product to be too small in size and not accepted by customers.

The magnetic poles of both powerful and ordinary magnets will not change, but we can use technical means to charge the same magnet with many poles. The premise of the magnet company is even numbers, which means that a magnet can have several N poles and corresponding S poles.

Magnetism is weakened by the influence of external environment, such as temperature changes, interference from other magnetic or electric fields, etc. Magnets of different materials have varying degrees of decay. To make a magnet that has lost its magnetism magnetic again, the magnet company can only use the method of magnetization, which is to magnetize the magnet again. Metal magnets, also known as strong magnets, have stronger magnetic properties than ordinary ferrite magnets because the surface magnetic field strength of the metal magnet after being magnetized is greater. This is determined by the physical properties of different magnetic materials.
