Question

A circular loop of wire lies in the plane of the paper. An increasing magnetic field points out of the paper. What is the direction of the induced current in the loop? The figure shows a bar magnet being pushed toward a conducting loop from below, along the axis of the loop. What is the current direction in the loop? Is there a magnetic force on the loop? If so, in which direction? Is there a force on the magnet? If so, in which direction? A 200-loop coil of cross sectional area 8.5 cm^2 lies in the plane of the page. An external magnetic field of 0.060 T is directed out of the plane of the page. The external field decreases to 0.020 T in 12 milliseconds. What is the magnitude of the total change in the external magnetic flux enclosed by the coil? What is the magnitude of the average voltage induced in the coil as the external flux is changing? If the coil has a resistance of 4.0 ohms, what is the magnitude of the average current in the coil?

Explanation / Answer

By the application of right hand rule, the direction of current is counterclockwise ( folded fingers ) as the field is out of plane. The induced current is in the opposite direction to the cause it generates. So, the induced current is in clockwise direction
