According to Faraday's Law, what effect does a magnetic field moving across a conductor have?

Faraday's Law of Electromagnetic Induction states that a change in magnetic field within a closed loop of wire induces an electromotive force (EMF) in the wire, which leads to the generation of an electrical current. This phenomenon occurs because the movement of the magnetic field across a conductor causes free electrons in the conductor to move, generating a flow of current. The relationship between the rate of change of the magnetic field and the induced current is direct, meaning that the faster the change, the greater the induced current.

This principle is foundational in the operation of many electrical devices, such as generators and transformers, which rely on the interaction between magnetic fields and conductors to create electrical energy. Thus, the correct answer highlights the essential link between a moving magnetic field and the production of electrical current as described by Faraday's Law.
