Direction: Q.31 to Q.35

The magnetic field lines of the Earth resemble that of a hypothetical magnetic dipole located at the centre of the Earth. The axis of the dipole is presently tilted by approximately \[11.3{}^\circ \] with respect to the axis of rotation of the Earth.

The pole near the geographic north pole of the Earth is called the north magnetic pole and the pole near the geographic south-pole is called south magnetic pole.

Read the given passage carefully and give the answer of the following questions:

                                The strength of the Earth's magnetic field varies from place to place on the Earth's surface, its value being of the order of:

A)             \[{{10}^{5}}T\]                     

B) \[{{10}^{6}}T\]

C)             \[{{10}^{-5}}T\]         

D)             \[{{10}^{8}}T\]
