Question 1
What does Faraday's first experiment demonstrate?
- That motion induces electricity
- That static electricity generates current
- That magnets repel each other
💡 Hint: Think about the role of movement in the experiment.
Question 2
True or False: The direction of induced current always opposes the change in magnetic flux.
- True
- False
💡 Hint: Remember Lenz's law when assessing the induced current.

Challenge Problems
Push your limits with challenges.
Question 1
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.
Question 2
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.
