NdFeB magnets should be noted that

 1. ndfeb magnet is the most powerful magnets ever invented by man, chunks of very strong magnetic force of

the magnet must be careful to pinch yourself.

   2. Put too close to the magnet NdFeB magnets is relatively fragile, strong magnetic drums force causes the two flew

together, resulting in damage to the magnets. The bulk magnet but be careful overfly

Debris injury to other parts of the eye.

   3. NdFeB magnet is easy to rust, so the magnet after plating. Plating is a surface moisture and high

temperatures and harsh environments such as plating only certain

Time rust. Corrosive things away from the magnet.

   4. NdFeB magnets very sensitive to high temperature, the N grades magnet up to 80 degree heat. Magnets of

different temperature levels respectively 80 100,120,150,180,200

The maximum temperature of 220 degrees.

   5. Credit cards, data storage card, older monitors TV is not close to a strong magnet.
