Calculate the force acting between two magnets of length `15cm` each and pole strength `80Am` each when the separation between their north poles is `10cm` and that between south poles is `40cm`.

Two magnets of length 10 cm each and pole strength 100 Am each are placed together such that separation between their south poles is 15 cm and that between their north poles is 35 cm. Calculate the force acting between the two magnets.

The magnetic moment of a length 10 cm and pole strength 4.0 Am will be

The distance between two magnetic pole is doubled and the pole strength of each is halved, the force between them will be

The force between two magnetic poles is F. If both the distance and pole strengths are doubled, then the force experienced is

A magnetic dipole of length 15cm has a dipole moment of 1-5Am^2 . What is the pole of strength?

A north pole of strength 50 Am and south pole of strength 100 Am are separated by a distance of 10 cm in air. Find the force between them.
