help plz with a question about Faradays law?

[paul]

My question states use Faradays law to calculate the Emf induced in a ring when it is flipped through 180 degrees in 0.2s assuming that the flux changes uniformly during this time? ring diameter is 2.2cm, the magnetic field strength is 48uT acting 66 degrees below the horizon. I know that Faradays law is Emf = change in flux / change in time but thats as far as I have got, could somebody point me in the right direction Plz, many thanks in advance

I'd like to help you especially since I see you're getting no answers. For me the difficulty is trying to understand what you mean by 48 micro Tesla "acting 66 degrees below the horizon". Where is this horizon - you never mentioned it before and what's it have to do with the problem? Edit your question with some explanation and maybe you'll get some help!! Oh also - how can the flux change uniformly?
