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
Magnetic flux density is also known as magnetic induction. When a magnetic material is placed in an external magnetic field then material gets magnetized. Such
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
The Magnetic flux Φ through any surface held in a magnetic field b is measured by the total number of magnetic lines of force crossing
Magnetic dipole moment is defined as the product of pole strength and the distance between the two poles. Let a → distance between the poles
Magnetic dipole consists of two equal and opposite magnetic poles separated by a small distance. When it is placed in an external magnetic field, it
The molecular theory of magnetism was given by Weber and modified by Ewing. According to this theory:
