## Main Question or Discussion Point

Hi, I been practicing for my physics compettiotion as I stumbled upon a difficult problem.I couldn't do I for days so I turned to internet in hope someone can help me.

The idea is as following: You have a frame made of wire and its area is S it rotates with a angular speed of W, in a magnetic field of induction B.The question is : "What's the intensity of the max Electromotive force?"

Thanks for your help! :)
