The shape of the block magnet is a block, and the magnets with the magnetic poles distributed on both ends are collectively called the block magnet. The common block magnets are rectangular, round and rod-shaped.
The magnetic force of the magnet is different. Some magnets have a large magnetic force, and some magnets have a small magnetic force. The magnitude of the magnetic force of different parts of the same magnet is also different. Take a block magnet as an example. The two ends of the block magnet have the strongest magnetism, and the magnetic field is weaker toward the middle.

The two poles with the strongest magnetism at both ends are called the two poles of the block magnet.
Block magnets are widely used in civil, industrial, communications, electronic and electrical equipment and instruments.

Manufacturing process of block magnet

The main raw materials of NdFeB magnets are: rare earth metal neodymium, rare earth metal praseodymium, pure iron, aluminum, boron iron alloy and other rare earth materials

Processing tool for block magnet

There are special slicers, wire cutting machines, flat grinders, double-sided machines, punching machines, chamfering machines, and electroplating equipment.

Process flow of block magnet

The manufacturing process of neodymium iron boron magnets, samarium cobalt magnets, alnico magnets, and ferrite magnets are also different. In terms of technology, there are sintered NdFeB magnets and bonded NdFeB magnets. We mainly talk about sintered NdFeB magnets.
Ingredients → smelting ingot → pulverizing → pressing → sintering and tempering → magnetic detection → grinding process → pin cutting process → electroplating → magnetization → finished product. Among them, the ingredients are the basis, and the sintering and tempering is the key NdFeB magnet production tools: smelting furnace, jaw breaking machine, ball mill, jet mill, compression molding machine, vacuum packaging machine, isostatic press, sintering furnace, heat treatment vacuum furnace, Magnetic performance tester, Gauss meter.

Magnetic field characteristics of block magnets

  • 1. The magnetic induction line around the magnet is from the N pole of the magnet and the S pole back;
  • 2. Magnetic induction lines will not cross;
  • 3. The place where the magnetic induction lines are dense and where the magnetic field is strong, the magnetic field is weak;
  • 4. The magnetic line of induction is a closed curve;
  • 5. The lines of magnetic field do not really exist, they are imaginary, and the magnetic field does exist.

China Block Magnets Manufacturer www.ymagnet.com supplies block magnets, rare earth neodymium block magnets, ndfe block magnets, rectangular neo permanent magnets , magnetic block magnets for scientific experiments or for industrial applications.

This product is not a toy and is not to be used by children. This product is to be used for scientific experiments or for industrial applications. This product contains strong Neodymium magnet(s) that can be harmful or fatal if swallowed. Strong Neodymium magnets are fragile, they are brittle and will break or chip if they hit a hard surface or are snagged together. Always use the utmost care when handling Neodymium magnets.
