Challenge Problems
Push your limits with advanced challenges
A coil has 100 turns and a magnetic flux that changes from 0.5 Tm^2 to 0.3 Tm^2 in 1 second. Calculate the induced emf.
💡 Hint: Focus on the number of turns and the change in magnetic flux over time.
In a setup where a magnet is thrust towards a coil quickly, describe qualitatively what happens to the induced current and how the system reacts.
💡 Hint: Think about how the current tries to maintain balance.
