Coercivity is higher

Vedclass · Answer

(C) material used for making a permanent magnet should have high retentivity so that it remains strongly magnetized even after the external magnetic field is removed.It should also have high coercivity so that it is not easily demagnetized by stray magnetic fields,temperature fluctuations,or minor mechanical impacts.Steel has higher coercivity compared to soft iron,which makes it more suitable for permanent magnets.Soft iron,on the other hand,has low coercivity and is therefore preferred for electromagnets where rapid magnetization and demagnetization are required.

Steel is preferred over soft iron for permanent magnets because
