  • 20 marks for incorrect answer

Hint

Use the right-hand thumb rule to determine the direction of the magnetic field produced by the current in the conductor XY.

Quick Oral Answer

The conductor XY will move towards the side AB of the loop due to the repulsion between the magnetic fields produced by the currents in the conductor XY and the loop ABCD.

Analysis & Explanation

This question requires the application of the right-hand thumb rule to determine the direction of the magnetic field produced by the current in the conductor XY. The correct answer is B, as the conductor XY will move towards the side AB of the loop due to the repulsion between the magnetic fields.

Common Mistakes

  1. 1assuming the conductor XY will remain stationary
  2. 2assuming the conductor XY will move away from the side AB of the loop

Interesting Facts

The magnetic field produced by a current-carrying conductor can be used to create a force on another current-carrying conductor.

This principle is used in many applications, including electric motors and generators.
