KCET2009PhysicsElectromagnetic Induction
Near a circular loop of conducting wire as shown in the figure an electron moves along a straight line. The direction of the induced current if any in the loop is
Options
- Avariable
- Bclockwise
- Canticlockwise
- Dzero
Correct answer
A. variable
Step-by-step solution
Since, electron is moving from left to right, the flux linked with loop will first increase and then decrease as the electron passes by. Therefore, induced current I in the loop will be first clockwise and then will move in anticlockwise direction as the electron passes by.
