Q1. A person uses an induction coil to heat a cup of water in the microwave. What phenomenon does the induction coil exploit?
Answer: Electromagnetic induction
Explanation: Thermal expansion, resistive heating and electromagnetic radiation are not the primary processes involved in heating the water. The induction coil uses electromagnetic induction to create the electric current in the water.
