HEY DEAR ...

⏺️Hysteresis is the dependence of the state of a system on its history. ... Hysteresis occurs in ferromagnetic and ferroelectric materials, as well as in the deformation of rubber bands and shape-memory alloys and many other natural phenomena.

⏺️ ♦ RETENTIVITY :
The magnetic field remaining in the material even after removing the external source is known as RETENTIVITY.
It tells us about magnetic strength of material.

♦ COERCIVITY :
The minimum value of magnetising intensity required to bring the material in its original state i.e. 0 magnetic field , is called COERCIVITY.
It tells us about the ability of material to not get affected by the stray magnetic fields.

HOPE , IT HELPS ...

COERICIVITY : - coericivity is the intensity of the applied magnetic field required to reduce the magnetization of a given material to zero . In other words to coerce the material to surrender its magnetism .

RETENTIVITY :- Retentivity is the capacity of an object to retain magnetism after the action of the magnetizing force has ceased .
