Lenz's Law states that any current induced will flow in a direction to oppose the action that caused the voltage to be induced.

• A. Not related
• B. False
• C. True
• D. Both

Answer: (C)

Induced currents always act to oppose the change that produced them. When the magnetic flux through a circuit changes, the induced current creates a magnetic field that counteracts that change, conserving energy. For example, moving a magnet toward a coil induces a current whose field repels the magnet, resisting the approach. If the magnet moves away, the induced field tries to keep the flux from dropping, effectively pulling it back. This opposing tendency is exactly what Lenz's Law describes, so the statement is true. The other options don’t fit because they deny or negate this real, observable behavior of induction.
