Question

The magnetic lines of forces due to the horizontal component of Earth's magnetic field will be

• A. circular
• B. elliptical
• C. curved
• D. horizontal and parallel

Answer 1

The correct option is D horizontal and parallel

Since it is horizontal component of earth's magnetic field therefore, it will be horizontal and parallel to the surface of the earth and field lines gives direction therefore, field lines will also be horizontal and parallel to earth's surface.
And at a particular point on earth field is almost uniform therefore, field lines will be parallel to each other.
