Homework Statement



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?

Homework Equations



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?

You have all the ingredients to put it together. The units of emf are Volts.
