What is the fundamental concept James Clerk Maxwell introduced that underpins our understanding of the connection between electricity and magnetism?

• Conservation of energy

• James' Law

• Faraday's Law

• Maxwell's equations

In Hans Christian Ørsted's experiment, what happened to the compass needle near a current-carrying wire when electricity passed through the wire?

• The needle aligned parallel to the wire.

• The needle formed a loop around the wire.

• The needle was deflected by the electric current.

• The needle showed no reaction to the current.

During Michael Faraday's electromagnetic induction experiment involving a magnet and a coil, what key observation was made?

• A steady current was generated.

• The current alternated.

• No interaction was observed in the coil.

• An electric current was induced in a nearby conductor.

James Clerk Maxwell's revolutionary equations are recognized for explaining which fundamental aspect of electromagnetic theory?
