Magnetic pole

  • * The poles of spherical magnets are usually at opposite ends of a certain diameter, such as the NS poles of the earth. Of course, there may be slight deviations, but usually not too much.
  • * For artificial spherical magnets, the poles are related to the direction of magnetization during the manufacturing process. There are many kinds of man-made magnet materials, but no matter which material it is, it will be magnetized after it is made into a certain shape. Therefore, its magnetic pole position is determined by the magnetization method. After the magnetization direction is determined, the magnetic poles will be at both ends of the diameter of the sphere in this direction.

Precautions

TemperatureWhen choosing NdFeB magnets, customers should choose their own magnet grades according to their working temperature. If the working temperature is higher than the bearing temperature of the magnet grades, the magnets will slowly demagnetize until there is no magnetism.
Before ordering, be sure to confirm the working temperature and the grade suitable for your own use.
EnvironmentIf the magnet device used is in a sealed state, you can consider choosing a magnet with no electroplating or white zinc plating on the surface, which can save costs. If the magnet is exposed to humid air, especially in the state of salt spray, it is recommended to consider the surface treated with nickel plating. magnet.
Magnets should be stored in a dry, constant temperature environment, separated and wrapped with plastic, wood chips, cardboard, foam, etc. It should be kept away from iron and easily magnetized items, such as monitors, bank cards, computers, TVs, mobile phones, etc.
Handling and stackingNdFeB strong magnetic material is hard, brittle, and has a strong magnetic field. It should be handled with care (especially large size and thin sheets). When the strong magnet itself or other iron objects attract or separate, be careful not to shock. Otherwise, the magnet may be damaged or fingers may be pinched due to collision. Because NdFeB is a multi-metal alloy material with a density between 7.45, it has the characteristics of heavy and brittle. So be careful when handling it to avoid magnetic shattering. During storage, the environment should also be kept dry. Do not stack them directly on the ground, but pad them with thick cardboard or place them on shelves.
Instructions for useWhen the magnets are attracted to each other and cannot be separated, it is recommended to push them horizontally and stagger them, and do not pull them hard. Use the left hand to fix the whole magnet, and use the index finger and thumb of the right hand to move out the magnet horizontally. Do not throw the removed magnet back into the magnet pile immediately after removing it. Please isolate the magnet immediately. Handle with care, keep away from iron or magnetic objects (about 16 cm) or wrap the removed paper with paper, so as to be safer. If you need to put the magnet back on the whole magnet, start slowly from the edge at a close distance. Be sure to hold the magnet in your hand until the magnet moves in.

Ordering Instructions

1. The higher the grade, the stronger the magnetism, and the higher the corresponding price, so the specific needs to be determined according to the actual needs of customers.

2. The sintered NdFeB magnet has an unimaginable super magnetic force. Theoretically, the sintered NdFeB magnet has a large suction force hundreds of times its own weight and is the most powerful permanent magnet at present. Of course, the larger the size of the magnet, the stronger the magnetic force.

3. Square length X width X height generally uses F to represent the square. For example, F50x25x13MM means that the length of the square magnet is 50 mm, the width is 25 mm, and the thickness is 13 mm. Generally, a number after the default indicates the magnetization direction of the square magnet. It is magnetization in the height direction. NS is on two large faces, that is, 50×25 faces.

Matters needing attention.

1. This product is suitable for people over 14 years old. The particles are small and easy to be swallowed by children. Use under adult supervision.

2. This product contains small parts, do not swallow, if swallowed, please see a doctor immediately.

3. Strong magnets may damage some electronic equipment, so please do not contact the magnetic ball electronic equipment or electronic medical instruments. Strong magnets can also destroy magnetic storage information, so please do not touch the magnetic ball with any magnetic storage products. Such as credit cards, and hard disk floppy disks.
