Magnetic Hysteresis
-
-
-
known as hystoresis loop, a representation of the mafnetizing force (H) versus the magnetic magnetic flux density (B) of a ferromagnetic material
-
these loop are important in the memory capacity of devices for audio recording or magnetic storage of data on computer disks
-
without magnetic field, exhibits paramagnetic, wherein their magnetic dipole moments are random and disordered as shown in fih=gure 1 a
when magnetic field applied, their dipole moments are aligned parallel and same direction as shown in figure 1 b
-
to reduce the magnetic flux back to zero, a coercive force must be applied wherein the dipole moments cancel each other out
