Question: Name five different basic devices that use at least one of the electromagnetic interactions and explain how they rely on them. Answer: 1. Electric motors convert electrical energy into mechanical energy using the interaction between electric current and magnetic field. 2. Generators or alternators convert mechanical energy into electrical energy by using electromagnetic induction when a coil rotates within a magnetic field. 3. Transformers change the voltage of AC using electromagnetic induction with coils of wire wound around a common core. 4. Electromagnets generate a magnetic field when an electric current flows through a coil of wire wrapped around a core and can be used in various applications. 5. Radio/television antennas receive electromagnetic waves in the form of radio signals, which are decoded by the radio or television using the interaction of electromagnetic waves with the electrons in the antenna structure.
