Electricity & Magnetism

Build an Electrical Logging Tool	The Electrical Resistivity of Materials	Fruit Power
While an oil well is being drilled, a logging tool may be lowered into the borehole to gather data that is used to produce a kind of graph known as a log. Try building a model of logging tool…	This experiment will help you understand how geologists can measure electrical resistivity to identify types of rock or detect oil underground…	Did you know that some of the fruits and vegetables you eat could also help you make electricity? Try this and see!
Building an Electromagnet
The nuclei of some atoms line up with a magnetic field, then "relax" when the field is removed. Try this experiment to see how this works.
