A Coil in a uniform magnetic field. Induced emf.
A 100 turn, 2.0 cm diameter coil is at rest in a horizontal plane.. A uniform magnetic field 60 degrees away from vertical increases from .50 T to 1.50 T in .60 s. What is the induce emf in the coil.
Mostly the problem I have with this one is determining the angle btw the B-Field and the plane of the area.
I believe the area plane should be pointing to the left. in which case in the equation for flux it would be the cos(30). Just double checking though.
Here is my diagram <http://img159.imageshack.us/img159/7747/areaplanebi6.jpg>
