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?
I assume we need a formula relating Area, B and emf - Faraday's law of induction? or possibly phi = BAcos(phi)
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?
