why can transformer coils store energy

SMES is an advanced energy storage technology that, at the highest level, stores energy similarly to a battery.

How does a coil work?

The underlying principle behind the functioning of a coil is known as electromagnetic induction, discovered by Michael Faraday. When an electric current passes through a coil, it creates a magnetic field around the coil. Likewise, when a magnetic field interacts with a coil, it induces an electric current in the wire.

Why are coils important in Electrical Engineering?
