Thanks to the powerful rare earth magnets, many items become smaller and smaller, such as smart phone, quartz watch and different kinds of precise instruments. Rare earth magnet in these items is mainly used as a part of micro motor.
China Magnets Source Material Limited manufactures many kinds of micro magnet (thin wall, many shapes) for quite a few applications. These applications include medical device, micro motors, micro sensors, quartz watch, optical isolators, and electro acoustic etc.
Our tiny magnets can be made of ndfeb, smco, alnico and ferrite magnet with multi coatings and shapes available.

Where can you get micro magnets in life?
If just need 1-2 piece micro magnets and don’t want to buy from store, you can get these small magnets from an abandoned earphone.
