Important Topics for HC Verma Concepts of Physics Part-2 Solutions Chapter 37: Magnetic Properties of Matter
The Magnetization of Materials and Intensity of Magnetization
Magnetization is also called magnet polarization. It is the density of magnetic moments that are induced in a magnetic object when it is placed near a magnet. When an electrical current is passed through any material, the magnetic effects of a material can be induced. The magnetic effect is caused by the spin of the electrons or the nuclei or by the motion of electrons in atoms.
The magnetic moment per unit volume of the object is known as the intensity of the magnetization of a magnetic object.
Paramagnetism and Ferromagnetism
Paramagnetism is a type of magnetism where some objects are weakly attracted by an external force on the applied magnetic field, and induced magnetic fields towards the direction of the applied magnetic field.
The basic device by which certain substances are attracted to magnets or form permanent magnets, this type of magnetism is known as ferromagnetism.
Magnetic susceptibility is defined as a dimensionless proportionality constant that demonstrates the degree of magnetization of substance in reply to an applied magnetic field.
Curie’s law is defined as paramagnetic material of magnetization that is proportional to an applied magnetic field. The magnetization is inversely proportional to temperature if the material is heated.
M=C × (B/T)
M = Magnetisation
B = Magnetic field which is measured in teslas
T = Absolute temperature which is measured in kelvins
C = Curie’s constant
Soft Iron and Steel
Soft iron gets magnetized very fast but loses its magnetism immediately when the inducing magnet is removed. Thus soft irons have low retentivity but high susceptibility. In making temporary electromagnets where strong but temporary magnets have required this property of soft iron is very useful. Soft iron is used to make the core in the transformer.
Steel gets magnetized slowly but retains the obtained magnetism for a long period of time. Steel has high retentivity but low susceptibility. They are used to make magnets.
