Paramagnetism Atoms, molecules or ions in the paramagnetic materials contain permanent magnetic moments. (When one or more electrons are transferred from an atom, it is…

Magnetic retentivity: The ability to retain the generated magnetization in a magnetic material when the magnetizing force is removed is called the magnetic retentivity of…

Magnetic coercivity: The ability to retain the generated magnetism in material, even though there exists all the factors for the decrease of magnetism is called…

Magnetic Intensity The magnetic intensity at a point is defined as the force that unit north – Pole experiences when it is placed in that…

Curie point: The temperature at which the magnetism of a magnet is completely destroyed is called curie point. It is the temperature at which certain…

Magnetic field intensity: The ratio of the magnetic induction or magnetic field to the magnetic permeability at a point in a magnetic field is called…

Magnetic permeability The ratio of the magnetic induction created in a medium to the magnetic intensity is called the absolute permeability or permeability of that…

Horizontal Intensity of Earth’s magnetic field: Elements of Geomagnetism Horizontal and vertical components of the earth’s magnetic intensity: The force acting on a unit pole…

Magnetic induction: When a magnetic material (for example a piece of iron) is placed in a magnetic field, it is observed that it has become…

Magnetic dipole moment: The moment associated with a magnetic dipole called magnetic dipole moment. If the pole strength of a bar magnet is ‘m’ and…
