option a is correct. When magnet is pushed initially, rightward magnetic field cuts through the loop, so current flows in a direction to oppose this, i.e. which creates leftward field, i.e. from R to L. Similarly, when the magnet comes out of the loop, the current flows in a direction to resist the change , so it flows L to R.

A coil is suspended around an axis which is colinear with the axis of a bar magnet.The coil is connected to a resistor with ends labeled “a” and “b”. The bar magnet moves from left to right with North and South poles labeled as in the figure. UseLenz’s law to answer the following question concerning the direction of induced currents and magnetic fields.What is the direction of the induced magnetic field in the coil when the bar magnet ismoving from...
A bar magnet is moving toward a solenoid of wire as shown at a constant speed v. The ends of the wire are connected across a light bulb as shown. The magnet flies through the solenoid and continues moving to the left. Which entry in the table below correctly indicates the behavior of the light bulb.as the magnet is heading toward the solenoid and as it is heading away from the solenoid? Hint: The brightness of the light bulb is...
Conceptual: A conducting loop of wire is oriented horizontally, and a magnet is falling downward, through the loop. (a) Draw the direction of the induced current that flows in the loop as the magnet falls downward. (b) Sketch and label the magnetic field lines that are created by the induced current in the loop. (c) Does this create an attractive or repulsive force between the loop and magnet?
Figure shows a bar magnet being pushed toward a conducting loop from below, along the axis of the loop. What is the direction of an induced current in the loop? Explain.
A bar magnet is oriented above a copper ring, as shown in the figure. The magnet is dropped and passes completely through the ring. As viewed from above, what is the direction of the current induced in the ring after the magnet has completely passed through the ring and is somewhat below it? There is no current in the ring. counterclockwise clockwise
Q4 A bar magnet is held above a loop of wire in a horizontal plane, as shown in Figure. According to the Lenz's law (write the Lenz's law), find the direction of the induced current through the resistor (a) while the magnet is falling toward the loop and (b) after the magnet has passed through the loop and moves away from it (draw the magnetic field lines of both the magnet and loop).
