Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What occurs during mutual induction?
- Current flows through one coil only
- A change in current in one coil induces emf in another coil
- Inductance is zero
💡 Hint: Think about the definition of mutual induction.
Question 2
True or False: Mutual inductance increases with greater distance between coils.
- True
- False
💡 Hint: Consider how magnetic fields behave over distance.

Challenge Problems
Push your limits with challenges.
Question 1
Two coils are placed 5 cm apart, and the first coil has a current changing at 1 A/s. If the mutual inductance between the coils is 2 H, calculate the induced emf in the second coil.
💡 Hint: Ensure you substitute the values accurately in the formula.
Question 2
If you are designing a wireless charging device, discuss how you would optimize the coil arrangement for maximum mutual inductance.
💡 Hint: Consider how magnetic fields interact.
