1. The problem statement, all variables and given/known data S is a disk of Area 0.003m2, B is a magnetic field perpendicular to S and increasing at 0.02 T per second. What is the EMF in the perimeter of S? 2. Relevant equations I assume we need a formula relating Area, B and emf - Faraday's law of induction? or possibly phi = BAcos(phi) 3. The attempt at a solution phi - BxA = .003x.02 = .00006 E = -N(phi)/t t = 1 second N = 1 therefore E = -.00006 is this right? what are the units of EMF?
