An induced emf is observed in a coil when a permanent magnet is moved toward the coil, Figure a). An induced emf is also observed when the coil is moved toward the magnet, Figure b). Explain how the induced emf in both cases is in accord with Einstein's first postulate.
A) The induced current in a) is in the clockwise direction, whereas it is in the anti-clockwise in b), indicating the difference in absolute motion.
B) The induced current in a) is in the anti-clockwise direction, whereas it is in the clockwise in b), indicating the difference in absolute motion.
C) The induced currents are in the clockwise direction for both cases, indicating that absolute motion cannot be detected.
D) The induced currents are in the anti-clockwise direction for both cases, indicating that absolute motion cannot be detected.
E) None of the above statements is correct.
