A point near the equator has: (H and V are horizontal and vertical components of Earth's magnetic field at a point)

Explain the horizontal and vertical components of earth's magnetic field.

What are horizontal and vertical components of earth's total magnetic field ?

If at a certain place B_H and B_V are horizontal and vertical components of earth's magnetic field respectively and delta is the angle of dip at the same place then

What is the horizontal component of Earth's magnetic field? If the horizontal and vertical components of Earth's magnetic field are equal then what is the angle of dip?

Time period of cillations of a magnet of magnetic moment M and moment of inertia l in a vertical plane perpendicular to the magneitc meridian at a place where earth's horizontal and vertical component of magnetic field are B _(H) and B_(v) respectively is

Let V and H be the vertical and horizontal components of earth's magnetic field at any point on earth. Near the north pole
