Metal coated magnet

Product Name: Metal Clad Magnet

What is a magnet

Magnets Magnets are composed of atoms such as iron, cobalt, and nickel. The internal structure of the atoms is quite special and they have a magnetic moment. Magnets can generate magnetic fields and have the property of attracting ferromagnetic materials such as iron, nickel, cobalt and other metals.

Three performance indicators of neodymium magnets

1. Remanence Br:

After the permanent magnet is magnetized to technical saturation and the external magnetic field is removed, the retained Br is called the residual magnetic induction. Standard 1.26T or more.

2. Coercivity Hc:

To reduce the B of the permanent magnet that is magnetized to technical saturation to zero, the strength of the reverse magnetic field that needs to be added is called magnetic coercive force, or coercive force for short. Standard 859KA/m. powerful neodymium magnet

3. Magnetic energy product BH:

It represents the magnetic energy density established by the magnet in the air gap space (the space between the two magnetic poles of the magnet), that is, the magnetostatic energy per unit volume of the air gap. Since this energy is equal to the product of the Bm and Hm of the magnet, it is called the magnetic energy product. Standard 260KJ/m³

Features of neodymium magnets

Also known as neodymium iron boron magnets, its chemical formula is Nd2Fe14B, which is a kind of artificial long-lasting magnet, which has stronger magnetic force so far. In many fields, it is possible to replace traditional pure iron magnets, alnico and samarium-cobalt magnets such as electric motors, instruments and meters, automobile industry, petrochemical industry and magnetic healthcare products. Can produce various shapes: such as disc magnets, ring magnets, rectangular magnets, arc magnets and other shapes of magnets.

Precautions for the use of neodymium magnets

● 1. Magnets are easily broken, so additional processing cannot be performed.

●2. The magnetic field generated by the magnet may have an adverse effect on the following items: mobile phones, computers, clocks and other electronic equipment.

●3. The output is very high and the use temperature is 80°C, which may cause the magnetic force to decrease.

●4. If the product is subject to a strong impact, it may cause damage. It may also cause the magnetic force to decrease.

●5.In order to avoid the product from being impacted, please keep a gap of 0.1~0.3mm or more.
