Challenge Problems
Push your limits with advanced challenges
Consider a setup with two loops of wire. If the current in the first loop decreases rapidly, describe the current induced in the second loop based on Lenz's Law.
💡 Hint: Think about how changing currents affect magnetic fields.
You have a coil of wire rotating in a magnetic field. If the speed of rotation is doubled, what happens to the induced emf?
💡 Hint: Consider the relationship between speed and induced current.
