23. Curie-Weiss Law:


24. Hysteresis:


25. Curie-Weiss Law:
    At temperature above Curie temperaure the magnetic susceptibility of ferromagnetic materials i s
    inversely proportional to T TC

i.e., Susceptibility

1

m

T T C

 

Where TC is Curie’s temperature

24. Hysteresis:
    The phenomenon in which the value of a physical property lags behind changes in the effect causing it.
