Challenge Problems
Push your limits with challenges.
Question 1
A coil is rotated in a magnetic field of strength 0.4 T. If the coil's area is 2 m² and is angled at 30° to the magnetic field direction, calculate the magnetic flux through the coil.
💡 Hint: Apply the magnetic flux formula, ensuring you use the cosine of the angle correctly.
Question 2
Discuss how the design of transformers utilizes Lenz's Law to maintain efficiency in energy transmission.
💡 Hint: Evaluate how magnetic flux alters with changes in the primary coil's current.
