1. The problem statement, all variables and given/known data A 7.40 cm diameter coil consists of 15 turns of circular copper wire 2.3 mm in diameter. A uniform magnetic field, perpendicular to the plane of the coil, changes at a rate of 7.29×10^−3 T/s . Determine the current in the loop. Express your answer using two significant figures. 2. Relevant equations magnetic flux = BA ε = -N Δmagnetic flux / ΔT 3. The attempt at a solution I'm still a little confused as what to do with the 7.40 cm and 2.3 mm (other than convert them to SI units). What I've done so far: -15 (7.29 * 10^-3 T/s) = ε ε = -0.109 V Was that a good place to start?
