How Do You Calculate the Length of Wire in a Generator Coil?

[thompson.1674]

Homework Statement

A generator uses a coil that has 80 turns and a 0.35 T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. Assuming that each turn of the coil is a square (an approximation), determine the length of the wire from which the coil is made.

Homework Equations

E=NABwsinwt
w=2pif

The Attempt at a Solution

Vpeak=sqrt2 * 120= 169.71
w=2pi(60)=376.99
169.71=80*A*.35*376.99*(sin367.99*t)
but where do i go from here?
