1. The problem statement, all variables and given/known data All I've been given concerning this problem is the diagram below and the instruction to solve for the total voltage at both voltmeters. Unfortunately, I am not sure whether this configuration counts as a electromagnetic coil, or whether it is simply two single-wire circuits, one for each voltmeter, connected at Points A and B. It also isn't clear from the diagram whether voltmeter #1, and its associated circuit, is in the same plane as the other voltmeter. The known data: radius = .1m (A = .01pi) magnetic flux density = 100w/m^2 or 100 Teslas frequency = 1000 kHz 2. Relevant equations I have been assuming that this each circuit is a coil (with one turn) and that I can use Faraday's Law: EMF = dphi/dt where phi = the magnetic flux = B*A*cos(theta) 3. The attempt at a solution Quite frankly, I'm stuck. I'm not sure what 'theta' represents. B*A = 100w/m^2*.01m^2*pi = pi webers, so flux = pi * cos(theta). Is theta the angle of the coil? And once I get phi, how to I use Faraday's Law?
