You're an electrical engineer designing an alternate the generator that changes a car's battery). Mechanical engineers specify a 10 cm diameter rotating cod, and you determine that you can ft 250 turns in this coil. To charge a 12-V battery, you need a peak output of 16 V when the alternator is rotating at 1100 rpm. What do you specify for the alternator's magnetic field? Express your answer to two' significant figures and include the appropriate units.
