What is the strength of the magnetic field

[warrior2014]

Homework Statement

The armature of an ac generator is a circular coil with 49 turns and radius 3.1 cm. When the armature rotates at 382rpm, the amplitude of the emf in the coil is 17.0 V. What is the strength of the magnetic field (assumed to be uniform) ?

Homework Equations

E = N.n.phi

The Attempt at a Solution

I solved for phi and got 18.35 (Webers) Wb. But, I need the answer in Tesla (T) and I am unsure how to do this. Please help!
