3. A circular loop of wire with radius r and resistance R is immersed in a uniform magnetic field pointing out of thescreen (B = BO):a) What is the flux through the loop?b) Now suppose B has the following time dependence:B = Bo cos wtwhere Bo and w are constants. Plot the flux and the induced emf for two full periods (from t = 0 to t = 4π/w) and,during this time internal, determine when the current flows clockwise and when it flows counter-clockwise.c*) Now suppose B is constant but the loop is mechanically rotated around the vertical with constant angular frequencyw as shown below:What is the induced current as a function of time?
