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

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

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 identical short bar magnets of magnetic moment M each are placed at distance r apart in end-on position, then magnetic force between both is

A bar magnet of magnetic moment 0.4 Am^(2) is placed in a uniform magnetic field of induction 5 xx10^(-2) tesla. The angle between the magnetic induction and the magnetic moment is 30^(@) . The torque acting on the magnet is

A small coil of radius 0.002 m is placed on the axis of a magnet of magnetic moment 10^(5) JT^(-1) and length 0.1 m at a distance of 0.15 m from the centre of the magnet. The plane of the coil is perpendicular to the axis of the magnet. Find the force on the when a current of 2.0 A is passed through it.
