Magnetism is one of the phenomena by which materials exert an attractive or repulsive force on other materials.This note provides us an information on magnetism and Coloumb's law.

A line perpendicular to the axis of a magnet that passes through the center of its two poles is called the equatorial line of the magnet. This note provides us an information about some terminology and magnetic field.

The measurements at two points are important: at a point on the axis and at a point on the equatorial line of the bar magnet. These are called end-on position and broadside-on position. This note provides us an information on magnetic field due to a bar magnet.

A point in the magnetic field of a bar magnet at which the resultant field intensity is zero is called neutral point. This note provides us an information on neutral points.

The magnetic moment of a dipole is numerically equal to the torque acting on the dipole when it is placed perpendicular to the direction of a uniform magnetic field of unit strength. This note provides us an information on torque experienced by a magnet in a magnetic field and tangent law.

Deflection magnetometer is an instrument used to measure the magnetic moment and polar strength of a bar magnet.This note provides us an information about deflection magnetometer and its application.

Oscillation magnetometer is used to find the magnetic momentum M, of a bar magnet. For this, the period of oscillation of the magnet is noted and its moment of inertia is measured.This note provides us an information on oscillation magnetometer.
