Question

Explain hysteresis curve with domain theory.

Answer 1

When a ferromagnetic material is magnetized in one direction, it will not relax back to zero magnetization when the imposed magnetizing field is removed. ... The lack of retraceability of the magnetization curve is the property called hysteresis and it is related to the existence of magneticdomains in the material

Answer 2

Answer:

Hysteresis. ... 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.
