**1. Homework Statement**

A 0.69m long and 0.69m wide loop is moved at a constant velocity of 0.81m/s from a region of zero magentic field into a perpendicular constant magnetic field of 0.21T. Calculate the magnitude of the induced voltage in the loop while it is entering the B-field

**2. Homework Equations**

EMF=-N*A*B/T

**3. The Attempt at a Solution**

I can plug in the numbers for the number of loops N (1), the area A (LxW), and the magnitude of the field B (.21T), but how do I find the time from just knowing the velocity?
