Here are the essential concepts you must grasp in order to answer the question correctly.
Lenz's Law
Lenz's Law states that the direction of an induced electromotive force (emf) and the resulting current in a closed loop is such that it opposes the change in magnetic flux that produced it. This principle is crucial for understanding how currents react to changes in magnetic fields, ensuring that the induced current works against the cause of its induction.

Electromagnetic Induction
Electromagnetic induction is the process by which a changing magnetic field within a closed loop induces an electric current. This phenomenon is foundational in understanding how coils and circuits interact, particularly when the magnetic field strength or orientation changes, leading to the generation of current in nearby conductors.

Resistance and Ohm's Law
Resistance is a measure of the opposition to the flow of electric current in a circuit, quantified in ohms. According to Ohm's Law, the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance. Changes in resistance can significantly affect the current flow, especially in circuits with varying conditions.
