## Homework Statement

A circular coil with 35 turns of wire and a diameter of 19 cm is placed in a magnetic field given by B(t) = 6 t^2 + 6 t + 2 T where t is time in seconds. The field is perpendicular to the plane of the coil. What is the induced EMF at t = 5 s?

## Homework Equations

E=-d(magnetic flux)/dtime

## The Attempt at a Solution

I found E to be 36.12 V but that's wrong. I'm not sure what's wrong. I did E=NAB/time.
