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 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 Both choices A and D.

Answer 1

As in loop induced current is in the counter clockwise so magnetic field due to this induced current is in the out of plane direction.so now accordind to lenz law , magnetic field due to horizontal wire is in the opposite direction of the magnetic field due to loop to oppose the emf means in the plane.

So in wire current should be flows to left and increasing or flows to the right and decreasing.

So both choice A and D are correct.
