The angle of dip is the angle
between the vertical component of earth's magnetic field and magnetic meridian
between the vertical component of earth's magnetic field and geographic meridian
between earth's magnetic field direction and horizontal line on magnetic meridian
between the magnetic meridian and the geographic meridian
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 $8 \times 10^{22}\, Am^2$, the value of earth 's magnetic field near the equator is close to....$Gauss$ (radius of the earth $= 6.4 \times 10^6\, m$)
The lines of forces due to earth's horizontal component of magnetic field are
A magnetic needle is placed on a cork floating in a still lake in the northern hemisphere. Does the needle together with the cork move towards the north of the lake
At a place, the magnitudes of the horizontal component and total intensity of the magnetic field of the earth are $0.3 $ and $ 0.6$ Oersted respectively. The value of the angle of dip at this place will be.....$^o$
