In India,the magnetic declination at Delhi is . . . . . . .

The earth's magnetic field lines resemble that of a dipole at the centre of the earth. If the magnetic moment of this dipole is close to $8 \times 10^{22} \text{ Am}^2$,the value of earth's magnetic field near the equator is close to $.... \text{ Gauss}$ (radius of the earth $= 6.4 \times 10^6 \text{ m}$)

The Earth's magnetic field at a certain place has a horizontal component of $0.3 \ G$ and the total strength of $0.5 \ G$. The angle of dip is:

At which place does the Earth's magnetism become horizontal?

The pole near the geographic north pole is called ...... . The pole near the geographic south pole is called ...... .

If a magnet is suspended freely such that it can rotate about its magnetic axis,in which plane does it come to rest?
