HereÍs a top-of the line demonstration model. It has a simple design that complements its large size, making it easy to follow as you point out the magnets, armature, brushes and terminals. Two of the coils are painted green and two are painted red to make them easier to distinguish. Demonstrate many principles involving electromagnetism: polarity of coils, the right-hand rule, the dynamo rule and the motor rule. An adjustable commutator helps you explain the behavior of series-connected and shunt-wound motors. You can also use it as a generator. If you add a suitable galvanometer, you can see the instrument register the current produced. Includes complete instructions to help you conduct an effective and informative demonstration. Size: 40cm high and 50cm wide. Requires a 6V battery or DC power supply.
WARNING: CHOKING HAZARD - Small parts. Not for children under 3 yrs.
