Question

A circular loop of wire is falling toward a straight wire carrying a steady current to the left as shown B = mu_0 i/2 pi r What is the direction of the induced current in the loop of wire? A. Clockwise B. Counterclockwise C. Zero D. Impossible to determine E. I will agree with whatever the majority chooses The loop continues falling until it is below the straight wire. Now what is the direction of the induced current in the loop of wire? A. Clockwise B. Counterclockwise C. Zero D. Impossible to determine E. I will oppose whatever the majority chooses

Explanation / Answer

11.2

we know while coil is coming toward wire ,it distance from wire is decreasing so magnetic field on coil due to wire is increasing so current will be such as it decreases the field(By Lenz law) .FIeld due to wire is in into the plane of paper so current will flow such as field due to it is in out of the plane of paper .By right hand rule ,current will be counterclockwise

11.3

if below the wire ,r is increasing so B will decrease so it will try to increase B(By lenz law)

B direction will be out of the plane of paper so I will be again counterclockwise
