In physics lab, ellen has been given the task of constructing a simple motor. she must find common household items at home and bring them to class the following day. her list of items include:
9 volt battery and leads, copper wire rotor, platform to hold the rotor, a magnet, and a wood base
she sets up her motor in physics lab the next day and finds that it works well. which statement below explains the flow of energy through ellen's motor?
a) battery--> electrical current--> copper wire rotor --> magnet--> mechanical energy
b) battery--> magnet--> electrical current--> copper wire rotor--> mechanical energy
c) magnet--> mechanical energy--> copper wire rotor--> battery--> electrical current
d) magnet--> copper wire rotor--> mechanical energy--> battery--> electrical current
