Faraday's Law states that a voltage is induced in a coil of wire due to what kind of change?

Faraday's Law of Electromagnetic Induction states that a voltage is induced in a coil of wire when there is a change in the magnetic field surrounding that coil. This law highlights the relationship between electric and magnetic fields, emphasizing that it is the change in the magnetic environment (environmental change) that generates the induced voltage.

When the magnetic field around the coil changes, be it through the motion of a magnet towards or away from the coil or a change in the strength of the magnetic field, it induces an electromotive force (EMF) in the coil. This is fundamentally about how environmental factors, particularly magnetic fields, affect electrical phenomena.

Thus, the correct identification of environmental change as the catalyst for induced voltage is aligned with the core principle outlined in Faraday's Law.
