Question

Assuming that the earth's magnetic field is due to a large circular loop of current in the interior of the earth's,what is the plane of the loop and what is the direction of current around it?

Answer 1

Answer:

Magnetic Field Pattern due to a Circular Loop Carrying Current. ... Each segment of circular loop carrying current produces magnetic field lines in the same direction with in the loop. The direction of magnetic field at the centre of circular coil is perpendicular to the place of the coil. i.e. along the axis of the coil.
