Additional Genecon Accessories Electricity 2 Simply add current via the Genecon to visually demonstrate the relationship between electricity and magnetism. 1 3 ElectroMagnet With this electromagnet your students can more easily visualize the relationship between electricity and magnetism. The large coils are perfect for applying the Right Hand Rule so students can discover the direction of the magnetic field they cause. The horseshoe shaped soft iron responds to the field by becoming magnetized only when you supply current. You can connect it to a battery, a transformer, or use the Genecon and have your students measure the amount of force they can create. P8-8100 $19 Hook Mass not included. 1 Electric Swing Apparatus Study the interaction between a current-carrying wire and a constant magnetic field with the Electric Swing Apparatus. The Swing Apparatus, instrumental in promoting an understanding of Fleming’s Rule and the production of alternating currents, includes a wooden swing holder, a coated copper wire swing, and a color-coded U magnet. P8-8009 $22 6 or more $19.50 each 2 Student Electrolysis Apparatus Use a Genecon to separate water into its component gases. A lot of cranking is required for this one, but student enthusiasm escalates once they are reminded that hydrogen is explosive. The tank is molded in one piece from a clear resin, with stainless steel electrodes sealed in place. The unique design permits stacking for storage. Complete with two graduated test tubes, a test tube holder and instructions. C6-0440 $35 6 or more $32 each 3 Ohm’s Law Experiment Kit Demonstrate the relationship between voltage, current, and resistance using this kit and a Genecon as a power source. Students will gain a better understanding of Ohm’s Law as they alter positions of clip leads along a nichrome wire and observe changes in the brightness of the attached bulb. This qualitative approach can be made more quantitative by adding an ammeter and voltmeter to the circuit. The kit consists of a 450 mm nichrome wire mounted on a wood base, a bulb, a socket, and alligator clip leads. Genecon sold separately on page 36.

Thermoelectric Device Heating or Cooling With a Turn of the Crank Just swing the buss bars in and out to change the circuitry. Use any or all of the bulbs at once! This fascinating accessory demonstrates the Peltier effect — the absorption or emission of heat energy when electrons move from one state to another across dissimilar semiconductor junctions. Just connect it to the Genecon, turn the handle in one direction, and the plate heats up. Reverse direction and the plate cools down! Thermoelectric circuits such as this allow temperature control when size or economics make normal cooling technologies impractical. They are used on circuit boards to cool components and in picnic coolers powered by car cigarette lighters. For an added challenge, ask your students to suggest more important or diverse applications for the device. P3-2600 $49 Series/Parallel Bulb Board No more wire nests! The five mini bulbs can be quickly arranged in series, parallel, or complex circuits, simply by adjusting the buss bars. 5 bulbs included. Size 38 cm x 13.5 cm.
