Question

How is the direction of induced current in a metal wire moving perpendicular to magnetic field found?​

Answer 1

Answer:

Direction of current induced in a wire moving in a magnetic field is found by using Fleming's right hand rule

Explanation:

By Right hand thumb rule the direction of magnetic field through ring 1 , due to current  in wire will be perpendicular inward into the plane of paper . Now according to Lenz's law ,  as the current is decreasing in wire , the direction of induced current in ring 1 will be such that , it should oppose the decrement of current in wire , for that  upper face of ring 1 will be a south pole . If upper face is south then direction of current in ring 1 is clockwise .

 Due to same reason the direction of induced current in ring 2 will be anticlockwise .
