1. The problem statement, all variables and given/known data A flexible wire loop has a radius of r = 0.178 m and it is inside a uniform magnetic field of B = 0.332 T. The loop is grasped at points P and Q and stretched until its area is zero. It takes 0.146 s to close the loop. 2. Relevant equations EMF = ∆Phi/∆t Phi = magnetic flux 3. The attempt at a solution Used the formula above. So where is current induced? In the wire? Due to the change in magnetic field then? Or magnetic flux? How do I find its direction... I mean, I know if you have magnetic field, then you use right hand rule, right? Anyway, how do I find direction here?
