A vertical wire carries a current in upward direction

Asked by admin @ 13/08/2021 in Physics viewed by 308 People

a vertical wire carries a current in upward direction . An electron beam sent horizontally towards the wire will be deflected a) towards right b) towards left c) upwards d) downwards

Answered by admin @ 13/08/2021

The answer is c. upwards.
Because when current is vertically upwards then according to right hand thumb rule the direction of magnetic field will be anticlockwise hence according Fleming's left hand rule , a horizontal beam gets deflected upwards.
Hope it helps you.
