Challenge Problems
Push your limits with advanced challenges
A generator has a coil with 200 turns, an area of 0.5 m2, and operates in a 0.2 T magnetic field. If the coil rotates at 60 revolutions per minute, calculate the maximum emf generated.
💡 Hint: Convert RPM to radians per second and remember to use the full formula carefully.
You design a new AC generator with improved efficiency. With what changes to the coil's material, magnetic field strength, and number of turns could you potentially enhance the induced emf?
💡 Hint: Reflect on the equation e = NBAω – how does each variable influence the outcome?
