Would the maximum possible magnetisation of a paramagnetic substance be of the same order of magnitude as the magnetisation of a ferromagnet ?

Distinguish between paramagnetic and ferromagnetic substances.

Explain qualitatively on the basis of domain picture the lireversibility in the magnetisation curve of a ferromagnet.

Susceptibility of a magnetic substance is found to depend on temperature and the strength of the magnetising field. The material is a

What type substances would make better permanent magnets, ferromagnetic or ferrimagnetic ?

Why does a paramagnetic sample display greater magnetisation ( for the same magnetising field ) when cooled ?

Mention the range of magnetic susceptibility for ( a) Diamagnetic substances ( DMS) (b) Paramagnetic substances (PMS) (c ) Ferromagnetic substances (FMS).

A domain in ferromagnetic iron in the form of a cube of side length 1mum . Estimate the number of iron atoms in the domain and the maximum possible dipole moment and magnetisation of the domain. The atomic mass of iron 55g/mole and its density is 7.9 g/cm^(3) . Assume that each iron has a dipole moment of 9.27 xx 10^(-24) A m^(2) .

A Rowland ring of mean radius 15 cm has 3500 tums of wire wound on a ferromagnetic core of relative permeability 800. What is the magnetic field B in the core for a magnetising current of 1.2 A?
