Starting from a time when the coil's plane is parallel to the magnetic field, calculate the average induce electromotive force whilst the coil is turning 0.5pi radians.

Please read forum requirements. They require you to show/tell us what you've done so far. If you can't figure out where to start we can give hints.

Right now I highly suggest that you look up the term "electromotive force".
