Paramagnetic materials have following properties: In paramagnetic materials, the magnetic lines of forces due to the applied field are attracted towards the paramagnetic material. When
Relative magnetic permeability of diamagnetic materials is always less than unity that is μr < 1 Explanation:
Diamagnetic materials have following properties: In a diamagnetic material, the magnetic lines of forces due to an applied field are repelled.
In an atom, electron revolves around the nucleus in a closed orbit. Since electron is a charged particle, so its orbit around the nucleus is
Relative magnetic permeability is defined as the ratio of permeability of medium (μ) to the permeability of free space (μ0) μr = μ/μ0 or μr
Magnetic permeability is defined as the degree to which the magnetic lines of force can penetrate or permeate the material. It can also be defined
It represents the extent to which a specimen is magnetised when placed in a magnetising field. Or in other words the intensity of magnetisation of
Magnetic intensity is same as magnetizing force. Therefore, it is also defined as the degree to which a magnetic field can magnetise a material is
The degree to which a magnetic field can magnetise a material is expressed in terms of magnetizing force. Consider a toroidal solenoid with n turns
When a magnetic material is placed in an external magnetic field then material gets magnetized. Such magnetism produced in the material is called induced magnetism
