Question

7. Two circular coils mounted parallel to each other on the same axis carry steady currents. If an observer between
the coils reports that one coil carrying a clockwise current i, while other is carrying a counter clockwise current
i, between the two coils, then there is
(1) Steady repulsive force
(2) Zero force
(3) A repulsive force
(4) A steady attractive force​

Answer 1

Answer:

4)A steady attractive force

Explanation:

Because if current flow the coil is clockwise direction then magnetic field is outside then coil behaves like north pole and if current flow the coil is anticlockwise direction then coil behaves like south pole. So attractive force are there because both coil have opposite pole
