Question

A metallic metre stick moves with a velocity of 2 m s−1 in a direction perpendicular to its length and perpendicular to a uniform magnetic field of magnitude 0.2 T. Find the emf induced between the ends of the stick.

Answer 1

EMF Induced is 0.4 V

Explanation:

Given,  

Length of the stick, l = 1 m

Magnetic Field, B = 0.2 T

Velocity of the stick, v = 2 m/s

Hence, We get ,  

Induced Emf, e = $B\times L \times V$ 

e = $0.2 \times 1 \times 2$  

e = 0.4 V
