Q1. A 30-year-old engineer places a copper coil near a power transformer. What phenomenon occurs when the magnetic field through the coil changes?
Answer: Electromagnetic induction
Explanation: Electromagnetic induction occurs when a changing magnetic field induces an electric field. Magnetic resonance is a phenomenon of nuclear spins, Faraday's law of electrolysis relates to electrolysis, and Gauss's law relates to electric field distribution.
