The magnetic field lines due to a bar magnet are correctly shown in

Define the intensity of magnetic field.

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.....$cm$

Magnetic dipole moment is a

A long magnetic needle of length $2\,L$, magnetic moment $ M$  and pole strength $m$ units is broken into two pieces at the middle. The magnetic moment and pole strength of each piece will be

A straight magnetic strip has a magnetic moment of $44 \mathrm{Am}^2$. If the strip is bent in a semicircular shape, its magnetic moment will be .. . . . . . .$\mathrm{Am}^2$ $\left(\right.$ Given $\left.\pi=\frac{22}{7}\right)$
