At a certain place,the horizontal component of earth's magnetic field is $\sqrt{3}$ times the vertical component. The angle of dip at that place is....$^o$

Assertion : In high latitudes,one sees colourful curtains of light hanging down from high altitudes.
Reason : The high-energy charged particles from the sun are deflected to polar regions by the magnetic field of the earth.

$A$ compass needle which is allowed to move in a horizontal plane is taken to a geomagnetic pole. It

At a certain place,the horizontal component of the Earth's magnetic field is $B_0$ and the angle of dip is $45^o$. The total intensity of the Earth's magnetic field at that place will be:

What is the most accepted scientific explanation for the origin of the Earth's magnetic field?

At a place,if the earth's horizontal and vertical components of magnetic fields are equal,then the angle of dip will be.......$^o$
