1. The problem statement, all variables and given/known data A rectangle circuit which has a resistor R and has a size l*w. The circuit is moving away from an infinite long wire which has a current i moving up along the wire with velocity v. Find the current moving in the resistor's side which far from the wire r. Here's the figure of the problem. http://imgur.com/RcAbgVN 2. Relevant equations Maybe Faraday's Law? Like, Φ = ∫ B ⋅ dA and ε = -dλ/dt . 3. The attempt at a solution I found that my answer is -μ0ilv/2πr. But I'm not sure about it.
