A 5-kg block is moving at 20 m/s. What is the magnitude of the motional EMF induced in a 2-turn coil on its surface?
Q1. A 5-kg block is moving at 20 m/s. What is the magnitude of the motional EMF induced in a 2-turn coil on its surface?
Answer: 2 × 10^-5 V
Explanation: Using Faraday's law of induction. Induced EMF is 2 * 5 * 20 * (1e-4) = 2e-3 V.
