A bicycle can be used to generate electric power by attaching a loop to the axle and letting it rotate in a magnetic field.  Suppose such a device is attached to a bicycle with a 55 cm diameter wheel.   Part a) What is the velocity (in m/s) of the bicycle do the generator’s angular velocity is 41 rad/s?   v1 =   Part b) What is the maximum emf of the generator when the bicycle moves at 4.5 m/s, noting that is was 16.5 V under the original conditions?     Part c) If the sophisticated generator can vary its own magnetic field, what field strength will it need at 10.00 m/s to produce a 9.00 V maximum emf?  Assume the couple has 1.00 by 3.00 cm rectangular coil with 100 turns.
