Example 1 · difficulty 4/5
A single-turn rectangular loop has height h and extends from x = 0 to a movable edge at x = a. A perpendicular magnetic field varies as B(x) = βx. If the edge moves so that da/dt = v, what is the instantaneous induced emf magnitude?
- A. βhav
- B. βhav/2
- C. βhv
- D. βha²/2
