Step-by-step explanation:
---------------------------------------------
The direction of magnetic field at the centre
of the circular loop depends on whether the
current in the loop flows in clockwise or
anticlockwise direction.When the current is in
clockwise direction, the magnetic field goes
into the side of wall.
when current is in clockwise direction the
direction of magnetic field (B) is towards
the circuit on the other hand when current
is in anticlockwise direction the direction of
magnetic field (B) is outwards the circuit.
