A magnetic dipole has a pole strength of 40 Am and magnetic length 20 cm. What is the magnetic induction at a point on its axis at a distance of 30 cm from the centre of the dipole? (mu_(0)/(4pi)=10^(-7)" Wb/Am")

A bar magnet has pole strength of 10 A-m and a magnetic length of 5cm. Find the magnetic induction at a point 10 cm from either of its two poles [ mu_o = 4pi xx 10^-7 XI unit].

A long bar magnet has a pole strength of 10 Am . Find the magnetic field at a point on the axis of the magnet at a distance of 5cm from the north pole of the magnet.

A long bar magnet has a pole strength of 10 Am . Find the magnetic field at a point on the axis of the magnet at a distance of 5cm from the north pole of the magnet.

A long bar magnet has a pole strength of 10 Am . Find the magnetic field at a point on the axis of the magnet at a distance of 5cm from the north pole of the magnet.
