Completely assembled, this open design is similar to diagrams in most textbooks and allows easy learning of motor-related principles. Magnets can be reversed to change direction of the motor’s rotation. To observe change of speed with current, use an external rheostat (not included). Motor can be used vertically or horizontally, for both experiments and demonstrations. Motor is lightweight and can be used with a 1.5V battery or external power supply that you provide. Instructions and storage case included.
