(a) What happens if a bar magnet is cut into two pieces : (i) transverse to its length. (ii) along its length?

The magnetic dipole moment of a bar magnet is directly proportional to volume of the bar magnetic . You are given a bar magnet of length I , magnetic pole strength m and magnetic dipole moment M . What will be the effect on dipole moment and pole strength if the bar magnet is cut into the two equal pieces ? (i) Along it length ? (ii) Transverse to its length ?

Magnetic length of a bar magnet is

A magnet is cut into two pieces. Write the poles of the broken pieces of magnets.

A piece of wire is of length 12 3/4mdot if it is cut into two pieces in such a way that the length of one piece is 5 1/4m , what is the length of the other piece?

Consider metal ring kept on a horizontal plane . A bar magnet is held above the ring with its length along the axis is held above the ring with its length along the axis of the ring . If the magnet is dropped freely the acceleration of the falling magnet is : ( g is accelration due to gravity )

A piece of metal is 3 inch (represented by in) long. What is its length in cm?

A copper ring is held horizontally and a bar magnet is dropped through the ring with its length along the axis of the ring. The acceleration of the falling magnet while it is passing through the ring is
