An electron moves along the line AB which lies in the same plane as a circular loop of conducting wire as shown in figure. What will be the direction of the current induced (if any) in the loop? A. The current will change the direction as the electorn passes byB. No current will be inducedC. The current will be clockwiseD. The current will be anticlockwise |

Answer» Correct Answer - A An electron moving along the straight line is like a current carrying straight conductor, with a magnetic field around it. As a result, the flux linked with the coil will increase when the electron approaches the coil in going from left to right. But when it goes away, the flux will start decreasing. so the induced current will change the direction from anticlockwise as it passes by. |
