360666 A compass needle whose magnetic moment is \({60 {Am}^{2}}\) is pointing geographical north at a certain place whereas the horizontal component of the earth's magnetic field is \({40 \mu {Wb} / {m}^{2}}\) and experiences a torque of \({1.2 \times 10^{-3} {Nm}}\). What is the declination of the place in degrees?

360667 At \(45^{\circ}\) to the magnetic meridian, apparent dip is \(30^{\circ}\) the true dip at there is

360668 A dip needle vibrates in the vertical plane perpendicular to the magnetic meridan. The time period of vibration is found to be \(2 \mathrm{~s}\). The same needle is then allowed to vibrate in the horizontal plane, and the time period is again found to be 2\(s\). Then the angle of dip is

360669 Assertion :
If a compass needle is kept at magnetic north pole of the earth, the compass needle may stay in any direction.
Reason :
Dip needle will stay vertical at the north pole of earth.
