Question

A circular loop carrying a current is placed on a horizontal surface

Answer 1

Answer:

a circular loop carrying current is placed on a horizontal surface the direction of magnetic field at the centre of the circular loop depends on whether the current in the loop following in clockwise or anticlockwise direction

the direction of magnetic field at the centre of the circular loop depends on

when the current is is in clockwise direction the magnetic field goes into the side of Wal if you reverse the direction of current flow the direction of magnetic field also get reversed the same applies to the point outside the loop but you should consider the magnetic field due to infinitesimal current elements to arrive as its magnitude
