[SOLVED] Emf in a rectangular loop

1. Homework Statement
A rectangular loop (area = 0.15 m^2) turns in a uniform magnetic field, B = 0.16 T. When the angle between the field and the normal to the plane of the loop is pi/2 rad and increasing at 0.70 rad/s, what emf is induced in the loop?


2. Homework Equations
Flux=B*A

EMF=-N (delta flux/delta time)


3. The Attempt at a Solution

Flux= 0.16T * 0.15 m^2 = 0.024

Not sure what to do for the EMF.
Divided pi/2 radians by 0.70 rad/s to find time of 2.24 seconds. Then divided the flux by the time so... 0.024/2.24=0.011V

Thanks in advance for your help!

Actually, I was making a silly mistake...answer was off by one decimal place because I misread the area to be 0.015 m^2. Pretty simple problem lol
