Diamagnetic materials are those in which the individual atoms or molecules or ions do not possess any net magnet moment of their own. When a
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
The molecular theory of magnetism was given by Weber and modified by Ewing. According to this theory:
The atomic theory of magnetism was given by Weber and modified by Ewing. According to this theory: Each and every molecule of a magnetic substance
Following are the some of the basic properties of magnets: A magnet attracts magnetic substances like iron, steel towards it. The attraction is maximum at
The magnetic effects in a magnetic material are due to the atomic dipoles in the materials. These dipoles arise due to the tiny current loops
