The motion of a conducting rod through a magnetic field creates a motional EMF E.If the rod accelerates to twice the speed,what will the motional EMF be? A)$\varepsilon$ B)2$\varepsilon$ C)$\varepsilon$/2 D)4$\varepsilon$ E)$\varepsilon$²

Question

Quizplus · Accepted Answer

Motional EMF is directly proportional to the velocity of the conductor moving through the magnetic field. As the rod accelerates to twice the speed, the motional EMF will also double. Therefore, the new motional EMF will be 2E. Option B is the closest to this answer.
