Hysteresis Loop
Hysteresis loop is the
term commonly used in branch of science called physics.
Hysteresis Loop shows relation between Magnetic Flux
Density and Magnetizing Force as shown in above diagram.
Hysteresis can be used in sciences to filter signals.
Hysteresis occurs when we repeatedly cycle the field up
and down. We can say in other way that need of
retraceability of the magnetization curve is the
property called hysteresis and it is concerned with
presence of magnetism in the material.

Hysteresis
phenomena occur in magnetic and ferromagnetic materials,
as well as in the elastic and electromagnetic behavior
of materials. When we magnetize a ferromagnetic material
in a particular direction, there will be no zero
magnetization when the applied magnetizing field is out.
It must be equal to zero by a field in the reverse
direction. If an alternating magnetic field is applied
to the material, its magnetization will make a loop
which we call hysteresis loop.
Example, a device
regulating temperature of system managing a electronic
heater may turn the heater on when the temperature drops
below X degrees, and keeping it on till the temperature
rises above Y degrees.
