The incorrect statement regarding the lines of force of the magnetic field $B$ is
Magnetic intensity is a measure of lines of force passing through unit area held normal to it
Magnetic lines of force form a close curve
Inside a magnet, its magnetic lines of force move from north pole of a magnet towards its south pole
Due to a magnet magnetic lines of force never cut each other
Some equipotential surfaces of the magnetic scalar potential are shown in the figure. Magnetic field at a point in the region is
The magnetic field to a small magnetic dipole of magnetic moment $M$, at distance $ r$ from the centre on the equatorial line is given by (in $M.K.S. $ system)
The dipole moment of a short bar magnet is $1.25\, A-m^2$. The magnetic field on its axis at a distance of $0.5$ metre from the centre of the magnet is
A magnetic needle is kept in a non-uniform magnetic field. It experiences
Due to a small magnet, intensity at a distance $x$ in the end on position is $9$ $gauss$ . What will be the intensity at a distance $\frac{x}{2}$ on broad side on position....$gauss$
