A thin square coil has 33 turns of conducting wire. It is rotating with constant angular velocity in a uniform magnetic field B of 0.420 T. At times there is NO magnetic flux through the coil, and at other times, there is the maximum possible flux. The graph below shows the magnetic flux F through ONE turn of the coil as a function of time.
1. What is the length of a side of the coil?
2. Calculate the angular velocity of the coil.
3. Evaluate the magnitude of the induced voltage in the coil, Vemf, at time t= 1.70 s.
4. Now connect the ends of the wire together to make a circuit. The electrical resistance of the coil is 3.14 ohm. Calculate the power dissipated at time t= 1.70 s.
