प्रश्न

The horizontal component of the earth’s magnetic field at a place is B and angle of dip is 60°. What is the value of vertical component of earth’s magnetic field at equator?

उत्तर

On the equator, the values of both angle of dip (δ) and vertical component of earth’s magnetic field is zero. So, in this case, Bv = 0.
