Magnetic Moments of Two Bar Magnets in Deflection Method: Deflection magnetometer works on the principle of tangent law. According to tangent law when two uniform…

Deflection magnetometer consists of a small magnetic needle pivoted on a sharp support such that it is free to rotate in a horizontal plane. A…

A magnetic needle suspended, at a point where there are two crossed magnetic fields acting at right angles to each other, will come to rest…

Consider a bar magnet NS of length 2l and pole strength m placed in a uniform magnetic field of induction B at an angle θ…

A bar magnet is placed on a plain sheet of a paper. A compass needle is placed near the north pole of the magnet. The…

Coulomb’s inverse square law states that the force of attraction or repulsion between the two magnetic poles is directly proportional to the product of their…

Uniform Magnetic Field: Magnetic field is said to be uniform if the magnetic induction has the same magnitude and the same direction at all the points in…

The number of magnetic lines of force passing through an area A is called magnetic flux. It is denoted by ϕ. Its unit is weber.…

The imaginary lines which represent the direction of the magnetic field are known as magnetic lines of force. Outside the magnet, their direction is from…
