Question

The figure shows a stationary conducting loop adjacent to a horizontal current-carrying wire. For which of the following conditions will a counter-clockwise induced current circulate in the stationary loop? Stationary conducting loop Counter- clockwise induced current 1 Current-carrying wire The current in the horizontal wire flows to the right and its value is decreasing. The current in the horizontal wire flows to the right and its value is increasing. The current in the horizontal wire flows to the left and its value is decreasing. The current in the horizontal wire flows to the left and its value is increasing. O Both choices A and D.

Answer 1

The answer is both choices A and D

For a counterclockwise induced current, the direction of induced magnetic field is out of the page. There can be two possibilities for this to happen.
i) When the direction of the magnetic field produced by the current-carrying wire is out of the page and decreasing. For this to happen, the current must flow to the right and its value must decrease (option A)
ii) When the direction of the magnetic field produced by the current-carrying wire is into the page and increasing. For this situation, the current must flow to the left and its value must increase (option D)
