Explanation: This phenomenon is described by **Lenz's Law**. It states that the direction of an induced electric current or electromotive force (EMF) is always such that it opposes the change in magnetic flux that produced it. In simpler terms, if you try to change the magnetic field through a coil, the coil will generate an opposing magnetic field to resist that change. This principle is a direct consequence of the conservation of energy in electromagnetic induction. Gilbert's law is not a recognized principle in electromagnetism in this context. Maxwell's laws are a set of fundamental equations describing all electromagnetic phenomena, and while Lenz's law is consistent with them (specifically Faraday's law with a negative sign), Lenz's law specifically details the *direction of opposition* described. Norton's law (Norton's Theorem) is a method for simplifying electrical circuits, unrelated to magnetic induction.
