## Homework Statement

S is a disk of Area 0.003m

^{2},

**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?
