Strong magnets should be kept away from iron and easily magnetized objects such as floppy disks, computer (TV) displays, bank CARDS, watches, mobile phones, medical devices (keep away from pacemakers!). And so on. Strong magnets should be stored in a dry, constant temperature environment. Large sizes should be separated and wrapped by plastic, wood chips, paper, hard foam, etc.

Ndfeb magnetic materials, as the latest development of rare earth permanent magnetic materials, are known as "magnetic wang" due to their excellent magnetic energy.

Ndfeb magnetic materials are neodymium, iron oxide and other alloys. Also called magnetic steel. NdFeB in English.

 

Neodymium ferroboron material contains a lot of neodymium and iron, easy to rust. So the ndfeb magnet must be coated. Surface chemical passivation is one of the best solutions. Nd-fe-b has high magnetic energy deposition and coercive force. Meanwhile, the advantages of high energy density make it widely used in modern industry and electronic technology, which makes it possible to miniaturize, lightweight and thin equipment such as instrument, electroacoustic motor and magnetic separation magnetization.

Ndfeb's advantages are high cost performance, with good mechanical characteristics; The disadvantage is that Curie has a low temperature point, poor temperature characteristics, and is prone to powder corrosion. Only by adjusting its chemical composition and adopting surface treatment method can it be improved to meet the requirements of practical application.

because of the characteristics of strong ndfeb magnetic material, hard, brittle, strong magnetic field, to be the only light (especially the large size and thin), good especially for magnetic suction comparison strong magnets, please use the left hand fixed magnet whole, right hand with your index finger and thumb, horizontal move out of the magnet, away don't throw away the magnet back immediately after the magnet heap, please immediately to the magnet isolation. Keep it light and away from the iron or magnetic objects (about 15cm) or wrap it in paper to make it safe. If you need to put the magnet back into the whole magnet, please slowly put it back and move it in close to the edge. The hand must hold the magnet until it has moved in. Push open at random, do not hard pry, must always be very careful operation not impact! Otherwise easy to cause because of collision damage magnet itself or splint fingers! Strong magnets should be kept away from iron and easily magnetized objects such as floppy disks, computer (TV) displays, bank CARDS, watches, mobile phones, medical devices (keep away from pacemakers!). And so on. Strong magnets should be stored in a dry, constant temperature environment. Large sizes should be separated and wrapped by plastic, wood chips, paper, hard foam, etc.
