Using plastic straws, wire, batteries and iron nails, student teams build and test two versions of electromagnets-one with and one without an iron nail at its core. They test each magnet's ability pick up loose staples, which reveals the...

This investigation has students examining how electric and magnetic charges are related. They will look at how an electric current is affected by the proximity of a magnet.

At the turn of the 19th century, scientists were beginning to gain a rudimentary understanding of electricity and magnetism, but they knew almost nothing about the relationship between the two. Baltic German physicist Heinrich Lenz took...

The history of electricity and magnetism starts with this special mineral possessing amazing, and still mysterious, properties.

Although he was not the first person to observe a connection between electricity and magnetism, Andre-Marie Ampere was the first scientist to attempt to theoretically explain and mathematically describe the phenomenon. His contributions...

Determine the mass and speed of a particle being fired through variable magnetic and electric fields. This problem is done after students determine the charge of an electron using the Millikan Oil Drop Experiment.
