53) The question asks us to find the induced electromotive force in the situation shown in the question. Using Faraday's law of induction we have a formula for the emf.

Where E is emf, Φ is flux, and t is time

We can substitute magnetic Field(B) * Area(A) for emf(Φ).

Where E is emf, B is magnetic field, A is area, t is time, L is length, w is width, and v is velocity

Answer: B
