5. A circular loop of wire with radius r and resistance R is immersed in a uniform magnetic field pointing out of the screen (B= Bo O): a) What is the flux through the loop? b) Now suppose Bo has the following time 00 dependence: 0 0 00 Bo= B cos wt where B and w are constants. Plot the flux and the induced emf for two full periods (from t = 0 to t = 4n/w) and, during this time interval, determine when the current flows clockwise and when it flows counter-clockwise. c) Now suppose Bo is constant but the loop is mechanically rotated around the vertical with constant angular frequency w as shown below: 0 0 0 0 0 0, 0 0 What is the induced emf in this case? What is the induced current? 0 0
