What are the cautions during operating or handling magnets?
Sintered NdFeB magnet is very brittle but hard. Its magnetic field is very powerful that can generate a force of 600 times of its weight. Caution should be to handle the magnet to avoid any damages to human body or the magnet itself. Some necessary protection method should be adopted when handling big block magnets. During installation, some fixture must be needed.12.Can NdFeB magnets be drilled and machined? Not easily or safely. Nd-Fe-B sintered magnets behave like a ceramic. They have tendency to crack and chip when drilled. Additionally, the powder produced when machining these magnets is flammable. Lastly, machining causes heat to build up in the magnet which may result in it being demagnetized. You need professional group to machine the exact NdFeB magnet for you, lot quantity, dimension and shape, and tolerance.13.If I have a Neo magnet with a Br of 12,300 Gauss, should I be able to measure 12,300 Gauss on its surface? No. The Br value is measured under closed circuit conditions
