Question

A conductor moving with a speed of 20m/s in the direction perpendicular to the direction of magnetic field of induction 0.5T, induces an EMF of 5V .the length of the conductor is

Answer 1

Answer:

1/2m or 0.5m

Explanation:

v= 20m/s , b= 0.5T , e= 5v and l=? using e= blv 5= 0.5(l) 20. 0.5(20) = 10 l= 5/10. then, l = 1/2m or 0.5 m
