In null method of comparison of magnetic moments, the net magnetic field at the centre of the DMM, when null deflection is obtained is
In both $\tan A$ and $\tan B$ positions in a Deflection Magnetometer, the bar magnet is always placed
The absolute value of earths magnetic horizontal intensity is determined with the help of
Among the following statements:
A) In $\tan A$ position of deflection magnetometer $B$ and $B _{H}$ are perpendicular
B) In $\tan B$ position of deflection magnetometer $B$ and $B _{H}$ parallel
The restoring couple for a magnet oscillating in the vibration magnetometer is provided by
Deflection magnetometer is held in $\tan B$ position. A magnet placed on one of its arms produces no deflection. This implies that the axis of the magnet is
The magnets of same magnetic moment $M$ and different lengths are placed in $tan\; A$ position. The fields at equal distances from them are :
A D.M.M is in tan A position in a region where $B _H$ is 50$\mu $T. When a magnet is placed at a suitable distance the deflection obtained is 45$^{0}$. The resultant magnetic field at the centre of the compass is
To measure the magnetic moment of a bar magnet, one may use.
