A small bar magnet has a magnetic moment `1.2 A-m^(2)`. The magnetic field at a distance `0.1 m` on its axis will be:
`(mu_(0)=4pixx10^(-7)T-m//A)`

A bar magnet 20 cm in length has a magnetic moment of 1 Am^2 . Calculate the magnetic field at a distance: (i) 0.5 m from its centre at a point on its axial line (ii) 0.6 m from its centre at a point on its equatorial line

Magnetic potential at a point due to a short magnetic dipole of moment 2 Am^(2) at a distance of 100 cm along a line making an angle of 60^(@) with the axis is (mu_(0)=4pixx10^(-7)Wb//Am)

A long solenoid has 200 turns per cm and carries a current of 2.5 amps. The magnetic field at its centre is (mu_(0)=4pixx10^(-7)"weber"//amp-m)

A long solenoid has 200 turns per cm and carries a current of 2.5 amps. The magnetic field at its centre is (mu_(0)=4pixx10^(-7)"weber"//amp-m)

A bar magnet has geometric length 4.8 xx 10^(-2)m . The magnet moment of bar magnet, of pole strength 20A m is?
