Product Description

Neodymium magnet ( NdFeBNIB or Neo), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymiumiron and boron.

Neodymium magnets have replaced alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets for a given application. Some examples are:

1.Head actuators for computer hard disks

2.Erase heads for cheap cassette recorders

3.Magnetic resonance imaging (MRI)

4.Mechanical e-cigarette firing switches

5.Locks for doors

6.Loudspeakers and headphones

7.Magnetic bearings and couplings

8.Benchtop NMR spectrometers

9.Electric motors:

a)Cordless tools

b)Servomotors

c)Lifting and compressor motors

e)Synchronous motors

f)Spindle and stepper motors

g)Electrical power steering

h)Drive motors for hybrid and electric vehicles.f neodymium

i)Actuators

10.Electric generators for wind turbines
