Question

Where on the earth’s surface is the value of the vertical component of earth’s magnetic field zero.

Answer 1

Hint: We know that earth has two poles, which are north and south. These poles create the magnetic field of the earth and this magnetic field extends in outer space to a very large extent. This magnetic field is known as a geomagnetic field. Now, this magnetic field has vertical and horizontal components. These components have different values at different points.

Complete step by step answer:
In the given question, we have to analyze the place where the value of the component of the earth’s magnetic field is zero.
Now, we know that earth has a very strong magnetic field. Earth itself is a very strong magnet.
We know that the vertical component of earth’s magnetic field will be zero when the magnetic field will be parallel to the surface. Now, we also know that earth has two poles but at the poles only the vertical component of the magnetic field is found and the horizontal component doesn’t exist there. Now, we know that the vertical component of the earth’s magnetic field is zero only at the equator because at this point the magnetic fields are parallel to the earth’s surface.

Hence, the correct answer for this problem is Earth’s equator.

Note: In the given question, we know that the magnetic field of any magnet has two components. Now, these components have different values depending on the angle between the magnetic field and surface of the magnet. Now, we know that earth is magnet and the vertical component will be zero when the field is parallel to the earth’s surface.
