## Electric Currents and Fields

Students will observe that the magnetic field created by a coil of wire is perpendicular to the plane of the coil. They will also see that the field is stronger with more current, and that the field reverses direction when the current reverses.

## Genecon and Lost Energy

Talk about hands on! Students love interacting with Genecons. There’s such a direct connection between cranking the handle and producing electricity. In my energy conservation unit, for example, students can experience energy as electrical current plus heat, sound and electromagnet static.

### Where Did the Energy Go?

Lots of experiments demonstrate energy transfer, but very few show students the law of energy conservation in action. This lab is one of the best, and though it’s very simple, the Genecons make it very exciting for students.

Attach two Genecons together so that one becomes the generator and the other the motor. Instruct students to practice generating electrical current by turning the generator’s handle 1 time. Next, ask students to predict how many handle turns will be produced in the motor when the generator is turned 10 times. Turn the generator 10 times as the students count how many times the motor’s handle actually turns. How can they explain the difference?

For example, if 10 energy units results in 7 energy units of output, what happened to the other 3? One unit produces sound (they can hear the current whirring). One unit produces heat (the energy graveyard!). And the last unit becomes electromagnetic energy.

To demonstrate this electromagnetic energy, put an AM radio between the generator and motor and tune it between stations. As students crank the generator, they actually hear energy being converted into electromagnetic static.

# Series Circuits

Several properties of a series circuit will be demonstrated in this experiment. The primary concepts to be covered are: 1. Lamps in series reduce current flow. 2. Lamps in series increase the total resistance of the circuit. 3. The voltage across each bulb in a series circuit decreases as the number of bulbs in the circuit increases.

Required Equipment
Genecon, 4 mini bulb bases, 4 mini bulbs, alligator leads, voltmeter, ammeter
