Last:What’s the technological process of NdFeB magnets? Next:Which areas are the Samarium cobalt (SmCo) magnet applied in?
The application of Chinese NdFeB magnets
At present, Chinese NdFeB magnets’ application is as follows:
The application of high technology products accounts for 37%, such as magnetic resonance imaging ( MRI ), mobile phone vibration, hard disk drive the voice coil ( VCM ), CD ( DVD, CD-ROM ) drive spindle, electric tools, electric vehicles, inverter air conditioner engine. Traditional in cheap product applications accounts for 63%, such as audio devices, magnetic devices, magnetic separator, a magnetizer.
The magnetic device with an internal core, using a current-carrying coil to make it like a magnet is called an electromagnet. It is usually made of strip or horseshoe. Core should be made of the magnetic soft iron or silicon steel, which is easy to be magnetized, and easy to disappear. The electromagnet has magnetic in electric, and it will disappear after the power cuts off. Electromagnet in daily life has an extremely wide application. The invention also makes the electromagnet generator power greatly improved.
