Question

An electron moves along the line AB which lies in the same plane as a circular loop of conducting wire as shown in figure. The direction of the induced electric field in loop will be

• A. no current will be induced
• B. clockwise
• C. anticlockwise
• D. the current will change direction as the electron passes by

Answer 1

Answer: (D)

the current will change direction as the electron passes by

If electron is moving from left to right, the flux linked with will first increase and then decrease as the electron passes by. So the induced current in the loop will be first anticlockwise and will change direction as the electron passes by.
