-a permanent magnet

-a source of electric current (battery)

-components called brushes and commutator

-the brushes and the commutator form a closed electric circuit]]> 2018-02-13 15:12:36 UTC https://padlet.com/vgrape/6y9r99gw7tp8/wish/231074804 Motor Power vgrape https://padlet.com/vgrape/6y9r99gw7tp8/wish/231078878 -when current flows in the coil the forces between the coil and the permanent magnet cause the coil to rotate

-coil continues to rotate

-inertia of the coil causes in to continue rotatating

-the coil has rotated so that the brushes are again in contact with the commutator

-the coil rotates until its poles are next to the opposite poles of the permanent magnet]]> 2018-02-13 15:18:43 UTC https://padlet.com/vgrape/6y9r99gw7tp8/wish/231078878 vgrape https://padlet.com/vgrape/6y9r99gw7tp8/wish/231086121
