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.
Solution
Given:-
Length of the stick, l = 1 m
Magnetic field, B = 0.2 T
Velocity of the stick, v = 2 m/s
Thus, we get
Induced emf, e = Blv = 0.2 × 1 × 2 = 0.4 V
