Physics Flashcards: Explain Electromagnetic Induction

Study Explain Electromagnetic Induction in Physics with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

A coil has N=200N=200 and flux per turn changes at dΦdt=0.01 Wb s−1\frac{d\Phi}{dt}=0.01\ \text{Wb s}^{-1}. Find ∣ε∣|\varepsilon|.

ANSWER

2 V2\ \text{V}. ∣ε∣=N∣dΦdt∣=200×0.01=2 V|\varepsilon| = N|\frac{d\Phi}{dt}| = 200 \times 0.01 = 2\ \text{V}.
