A)24 V
B)2.4 V
C)0.24 V
D)0.60 kV
E)6.0 V

Quizplus · Accepted Answer

The induced potential difference (emf) in a conductor moving in a magnetic field is given by $emf = Bvl$, where $B$ is the magnetic field strength, $v$ is the velocity of the conductor, and $l$ is the length of the conductor. Substituting the given values: $emf = 0.080 \, \text{T} \times 12 \, \text{m/s} \times 0.25 \, \text{m} = 0.24 \, \text{V}$.
