Magnetic Substances

Can we have magnetic hysteresis in paramagnetic or diamagnetic substances?

Which of the following is not showing the essential difference between electrostatic shielding by a conducting shell and magnetostatic shielding?

A paramagnetic material is kept in a magnetic field. The field is increased till the magnetisation becomes constant. If the temperature is now decreased, the magnetisation ___________ .

When a ferromagnetic material goes through a hysteresis loop, its thermal energy is increased. Where does this energy come from?

A paramagnetic material is placed in a magnetic field. Consider the following statements:-
(A) If the magnetic field is increased, the magnetisation is increased.
(B) If the temperature is increased, the magnetisation is increased.

The property of diamagnetism is said to be present in all materials. Then, why are some materials paramagnetic or ferromagnetic?

A rod is inserted as the core in the current-carrying solenoid of the previous problem. (a) What is the magnetic intensity H at the centre? (b) If the magnetization I of the core is found to be 0.12 A m⁻¹, find the susceptibility of the material of the rod. (c) Is the material paramagnetic, diamagnetic or ferromagnetic?
