You finish building your motor, but you are disappointed with how slow your magnet is spinning. What ways can help you significantly increase the speed of your motor? Select all that apply. O Increase the current (but not so much as to melt the wires!) Use a stronger permanent magnet. Cover the entire nail with whiteout. Use a copper penny over a nickel. O Invert the wrapping direction of your coils (i.e. counterclockwise instead of clockwise, or vice versa) Use a longer wire to coil around the motor. O Use the same length of coil wire, but wrap it on either side of the magnet
