Magnetic field of a solenoid | Magnetic field lines | Magnetic flux and Gauss law for magnetism

A neutral point is found on the axis of a bar magnet at a distance of 10cm from one end. If the length of the magnet is 10cm and H=0*3gauss , find the magnetic moment of the magnet.

In case of a bar magnet, lines of magnetic induction

Inside a bar magnetic the magnetic field lines

The bar magnet produces magnetic induction of 4 xx 10^(-5)T at a point 10 cm from centre on the axis of magnet. The magnetic moment is The bar magnet produces magnetic induction
