The incorrect statement regarding the lines of force of the magnetic field $B$  is

A short magnet of moment $6.75\, Am^2$ produces a neutral point on its axis. If horizontal component of earth's magnetic field is $5 \times {10^{ – 5}}\,Wb/{m^2}$, then the distance of the neutral point should be…..$cm$

Two short magnets of magnetic moment $1000$ $A{m^2}$ are placed as shown at the corn ers of a square of side $10\, cm$. The net magnetic induction at $P$ is….$T$

A bar magnet of magnetic moment $M$ is placed at right angles to a magnetic induction $B.$ If a force $F$ is experienced by each pole of the magnet, the length of the magnet will be

The magnetic moment of a magnet of length $10\, cm$  and pole strength $ 4.0\, Am$  will be……$A{m^2}$
