what is coercivity and retentivity?

Asked by mehaksaini | 24th Dec, 2009, 07:27: PM

Expert Answer:


Coercitivity is the intensity of the magnetic field needed to reduce the magnetisation of a ferromagnetic material to zero after it has reached saturation...


Retentivity is the power of remaining magnetised after the force of magnetisation is stopped.

Hope this helps.
