Position the armature in the paper clip loops, with the shiny, uncolored side touching the paper clips. Make sure it doesn’t touch the magnet. If your motor doesn’t start immediately, try giving it a start by spinning the wire bundle. Since the motor will only spin in one direction, try spinning it both ways.
