Students are studying the connection between electricity and magnetism. They have been tasked with building a simple electric motor. One group collected these various materials:
9 volt battery
wire for leads
copper wire rotor
platform to hold the rotor
magnet
wood for a base
The students constructed their motor and found, once completed, that it worked! Which statement below explains the flow of energy through the group'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
