154455 A wire of length $6.28 \mathrm{~m}$ is bent into a circular coil of 2 turns. If a current of $0.5 \mathrm{~A}$ exists in the coil, the magnetic moment of the coil is, in A-m ${ }^{2}$

154456 A short bar magnet placed at a certain distance from a deflection magnetometer in tan $A$ position produces a deflection of $60^{\circ}$. The magnet is now cut into three equal pieces. If one piece is kept at the same distance in $\tan A$ position from the deflection magnetometer, then the deflection produced is

154457 The period of oscillation of a magnet at a place is 4 second. When it is demagnetized, so that the pole strength becomes 4 times the initial value, the period of oscillation in second is:

154458 A magnet of magnetic moment $M$ is cut into two equal parts (parallel to its length). The two parts are placed perpendicular to each other, so that their north poles touch each other. The resultant magnetic moment is:
