Explanation:
Coils carrying currents in opposite directions:
When two circular coils are mounted parallel to each other on the same axis and carry steady currents, the magnetic fields produced by the currents interact with each other. In this case, one coil is carrying a clockwise current and the other is carrying a counterclockwise current. Let's analyze the magnetic fields produced by these currents and their interaction.
Magnetic Field Due to a Current-Carrying Coil:
When a current flows through a wire, it produces a magnetic field around it. The magnetic field produced by a current-carrying coil is similar to that of a bar magnet. The magnetic field lines around a circular coil are concentric circles in the plane perpendicular to the coil's axis.
Magnetic Field Interaction:
The magnetic field produced by a current-carrying coil exerts a force on any other current-carrying coil placed in its vicinity. The direction of the force depends on the relative orientations of the magnetic fields.
Repulsive Force:
When the currents in the two coils flow in the same direction (clockwise in this case), their magnetic fields have the same orientation. According to the right-hand rule, the magnetic field lines around each coil will point in the same direction. Since like poles repel each other, the interaction between the magnetic fields will result in a repulsive force between the coils.
Attractive Force:
When the currents in the two coils flow in opposite directions (clockwise in one coil and counterclockwise in the other), their magnetic fields have opposite orientations. According to the right-hand rule, the magnetic field lines around each coil will point in opposite directions. Since opposite poles attract each other, the interaction between the magnetic fields will result in an attractive force between the coils.
Conclusion:
In this case, one coil is carrying a clockwise current and the other is carrying a counterclockwise current. The magnetic fields produced by these currents have opposite orientations. Therefore, the interaction between the magnetic fields will result in a steady attractive force between the two coils. Hence, the correct answer is option 'D' - a steady attractive force.
