Calculate the force acting between two small magnets, placed in end on position `0.1 m` apart from their centres. (Given, magnetic moment of each magnet is `5 Am^(2)`).

Two small magnets each of magnetic moment 10 Am^2 are placed in end on position 0.1m apart from their centres. The force acting between them is

The small magnets each of magnetic moment 10 A-m^(2) are placed end-on position 0.1 m apart from their centres. The force acting between them is

A short bar magnet is placed along positive X-axis with its centre at origin. Calculate the magnitude of magnetic field strength at point (0,5 cm), if the magnetic moment of the bar magnet is 0.5 Am^2

A short bar magnet has a magnetic moment of 0.2 JT(-1) . Calculate the magnitude of the magnetic field produced by the magnet at a distance of 8 cm from the centre of the magnet on the equitorial line of the magnet.

magnetic moment of a small bar magnet is 1A.m^(2) What will be the magnetic field at a point 1 m away from the centre of the magnet along its length?

Two magnets each of magnetic moment M are placed so as to form a cross at right angles to each other. The magnetic moment of the system is
