Electric Currents and Fields
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...

Genecon and Lost Energy
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...

Series Circuits
Series Circuits

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