Regarding neodymium iron boron powerful square (block) magnets, there are not many introductions on the Internet. Today, the magnet manufacturer Carrick Xiaofu introduced the direction of the square magnet and its production cycle in detail.
Let me talk about the delivery time of NdFeB square magnets: The delivery time of square magnets is related to the order quantity and processing difficulty. Generally, it takes about 7-10 days. This delivery time is related to the order and production volume of the magnet manufacturer. Confirm the magnet After the unit price, the delivery date has to be further negotiated. Don't be unhappy with the delivery date!
NdFeB square magnets are different from NdFeB disc magnets. Disc magnets are magnetized axially and radially. If you don't understand, you can read this article "Axial and radial magnetization of magnets. Introduction to Magnetization. The neodymium iron boron square magnet has thickness magnetization and side magnetization.
The figure below is a schematic diagram of the magnetizing direction of a square neodymium iron boron magnet
Many people don't know how to magnetize a square magnet, and they don’t know how to express it, so customers often make mistakes. For example, a square magnet is 15mm long, 4mm wide, and 3mm thick. It is expressed as F3*15*4, and 4 is the magnetizing direction. For example, a square magnet with a width of 9mm, a height of 7mm, and a length of 25mm needs to use the magnetic force of the 2 ends of the magnet. It is expressed as F7*9*25, which is the magnetization method of the third picture. It is really unclear. Welcome to point it out in the above picture. Send us the magnetizing method you need.
