Magnetism

Properties of Paramagnetic Materials Paramagnetic materials show the following properties It can be said that the materials which acquire a small amount of magnetism towards…

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…
