Earth’s Magnetic Field
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° 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.
At a place, angle of dip is 30°. If horizontal component of earth’s magnetic field is `H_e`` then the total intensity of magnetic field will be
Options:
(a) `H_e'/'2`
(b) `2H_e'/'sqrt3`
(c) `H_esqrt(3'/'2)`
(d) `2 H_e`
