Coil of Wire

Answer 30

Coils wound around the armature of an electric motor that become electromagnets to create turning

Question 31

Commutator

Answer 31

A switch in an electric motor that reverses current to assure that the coils push the armature in the same direction

Question 32

Brushes

Answer 32

Conductive contacts of an electric motor that bring electricity to the armature coils, slowly wear out over time

Question 33

Cap

Answer 33

End cap to hold components like brushes in an electric motor and keep stability
