Which term describes a continuous winding arrangement of a conductor which, when energized, creates a magnetic field turning electrical energy into mechanical energy?

• A. Condenser
• B. Coil
• C. Conductors
• D. Circuit

Answer: (B)

A coil is the continuous winding of a conductor that, when energized, creates a magnetic field and turns electrical energy into mechanical energy. As current flows through the turns, a magnetic field is produced, with strength depending on the current and the number of turns. In electric machines, these windings are arranged around a core so the magnetic field interacts with other magnets to generate torque and rotate the machine, delivering mechanical energy. The iron core helps concentrate the flux for better efficiency. The other terms refer to different things—condensers store energy as a capacitor, conductors are the wires themselves, and a circuit is the complete path for current—so the winding arrangement that drives motion is a coil.
