1. The problem statement, all variables and given/known data A 4.0 cm diameter coil (1000 turns) is at rest in the XY plane. The magnetic field in this region of space is given by B=(0.30i + 0.50t2 k) What is the induced EMF in the coil at t=2.0 seconds 2. Relevant equations ε=dΦ/dt Φ=ABcosθ 3. The attempt at a solution ε=d/dt( πr2)(0.03i+0.5t2 k) Cosθ ε=πr2cosθ *0.5*2t k Using trig I found θ=59° and plugging in the numbers I got ε=0.00129V k I assume I did something wrong. Is this anywhere close to the proper method?
