Question

Define magnetisation of a sample.

Open in App

Solution

Magnetisation of a sample is defined as the magnetic moment per unit volume of the sample. It is denoted by $M$ .
Mathematically, magnetisation of sample $M = \frac{μ}{V}$
SI units of magnetisation is Ampere per metre i.e. $A m^{- 1}$ .

Q. Answer the following questions:
(a) Why does a paramagnetic sample display greater magnetisation (for the same magnetising field) when cooled?
(b) Why is diamagnetism, in contrast, almost independent of temperature?
(c) If a toroid uses bismuth for its core, will the field in the core be (slightly) greater or (slightly) less than when the core is empty?
(d) Is the permeability of a ferromagnetic material independent of the magnetic field? If not, is it more for lower or higher fields?
(e) Magnetic field lines are always nearly normal to the surface of a ferromagnet at every point. (This fact is analogous to the static electric field lines being normal to the surface of a conductor at every point.) Why?
(f) Would the maximum possible magnetisation of a paramagnetic sample be of the same order of magnitude as the magnetisation of a ferromagnet?
