Well, I do know how to do this, and I seem to be hanging around. The basic equation is

flux = B A cos (theta)

where B is the strength of the mag field, A is the area of the loop, and theta is the angle between them, you are given flux and theta, and can easily compute the area using pi r^2, then all you have to do is solve for the magnetic field strength B:

B = flux / (pi r^2 cos 75)

I'm pretty sure that anyone who knew the answer to that question would not currently be hanging around on Yahoo Answers.

However, I can help you with English, if you would like.
