Question3
25.0ts An experimental electric motor uses coils made of 1300 turns ot wire wound on rectangular frames with dimensions 13.7 x 21.7 inches.The coils are fed(one w one as the motor turns)by a 96 volt battery pack and each coil has a combined resistance(all 1300 turns)of 2.37 Q.Calculate the minimum magnetic field strergth that must be provided by the field coils if the motor is to have a maximum torque ot 37.7ft1b.
