Question

What is the mathematical expression for Faraday's Law of electromagnetic induction?
Options
A ε = -N (ΔΦ/Δt)
Correct Answer
B ε = N (ΔΦ/Δt)
C ε = - (ΔΦ/Δt)
D ε = -N (Δt/ΔΦ)
Correct Answer

Option A is the correct answer.

Detailed Explanation

Faraday's Law states that the induced emf (ε) equals -N times the rate of change of magnetic flux (ΔΦ/Δt), where N is the number of turns and the negative sign indicates Lenz's Law.

Hint

emf = -N × (flux change / time).
