Energy can be stored in a magnetic field of:
Correct answer: A. Inductor
- A. Inductor
- B. Resistance
- C. Solenoid
- D. Capacitor
Explanation
Energy can be stored in a magnetic field of an Inductor.Inductors are passive electrical components typically consisting of a coil of wire wound around a core material. When current flows through an inductor, it creates a magnetic field around the coil. This magnetic field stores energy in the form of magnetic potential energy. When the current through the inductor changes, the magnetic field also changes, and energy is either stored or released from the magnetic field. Therefore, inductors can store energy in their magnetic fields.

About Electromagnetic Induction
Changing magnetic flux induces an emf according to Faraday's law, while Lenz's law gives the direction that opposes the change producing it. Transformers apply induction between coils to step alternating voltage up or down, with turns ratio, current transformation and energy losses determining practical operation.
