Hysteresis is the delay between an observed outcome and the quantity of change applied.
When a ferromagnetic material is magnetized in one direction, it will not relax back to zero magnetization when the imposed magnetizing field is removed. It must be driven back to zero by a field in the opposite direction. If an alternating magnetic field is applied to the material, its magnetization will trace out a loop called ahysteresis loop. The lack of retraceability of the magnetization curve is the property called hysteresis and it is related to the existence of magnetic domains in the material. Once the magnetic domains are reoriented, it takes some energy to turn them back again. This property of ferrromagnetic materials is useful as a magnetic "memory". Some compositions of ferromagnetic materials will retain an imposed magnetization indefinitely and are useful as "permanent magnets". The magnetic memory aspects of iron and chromium oxides make them useful in audiotape recording and for the magnetic storage of data on computer disks.
Variations in Hysteresis Curves
There is considerable variation in the hysteresis of different magnetic materials.

What is the significance of looping?
In hysteresis materials it represents the energy dissipated in them during the cycle of magnetization & demagnetization (just refer any hysteresis loop diagram) . This is used in many applications especially in aerospace to damp the oscillations in satellite.
Can you measure hysteresis loss for diamagnetic materials?
what is hysteresis losses
What is Hysteresis motor working principle?
It is a special type of synchronous motor.It works on the principle of hysteresis and the torque is produced due to hysteresis
Diagram of hysteresis motor?
can Hysteresis motor use like alternator
How do you calculate hysteresis?
max hysteresis = max(O_decreasing - O_increasing) / (O_max - O_min)
What is hysteresis and dead zone?
Hysteresis is a phenomena which dipicts different output effect with loading and unloading
What are the release dates for Hysteresis - 2012?
Hysteresis - 2012 was released on: USA: 1 October 2012
Operation principle of hysteresis motor?
Give a brief idea of principle of hysteresis motor,application.
What is hysteresis loop in stress and strain?
the leading or lagging between the stress and strain is called hysteresis loop
How can you measure the hysteresis loop of the ferroelectric materials and what is the name of the instruments used for the measurements of the hysteresis loop?
it is agm or vsm
How does one receive hysteresis?
Hysteresis occurs most commonly in ferromagnetic and ferroelectric materials such as rubber bands and shape-memory alloys. When the material is flexed the atoms often break apart causing hysteresis.
What is hytsteresis?
A misspelling of the word "hysteresis".
