How a Permanent Magnet Works

When the permanent magnet is magnetized in a strong magnetic field all the atomic moments are aligned to the same direction and once there, are held in 'lock-step' with each other (Fig. 2). The 'lock—step' allows the magnet to retain its magnetism on removal from the magnetic field and also resists the effect of a field applied in the reverse

Permanent Magnets an overview ScienceDirect Topics

The attractive permanent magnet properties of Fe 14 Nd 2 B 1 magnets arise from several factors (1) the large uniaxial magnetic anisotropy (K u = +5 × 10 6 J/m 3) of this tetragonal phase, (2) the large magnetization (B s = 1.6 T) owing to the ferromagnetic coupling between the Fe and Nd moments; and (3) the stability of the 14-2-1 phase

Difference Between Permanent Magnet and Temporary Magnet

Jun 29, 2020 · The permanent magnet is usually considered more stable than the other types of temporary magnets. The domains in a permanent magnet are considered as permanently aligned and cannot easily be brought back to its dimensionless motion. The magnetic poles of the permanent magnet cannot be easily changed and cannot reverse its direction.
