This Exploratorium activity shows the magnetic forces between nearby current-carrying wires. You'll find the materials needed, directions, an explanation of what happens, and links to related activities. This activity is part of Exploratorium's Science Snacks series.
6-8: 4G/M3. Electric currents and magnets can exert a force on each other.

4. THE PHYSICAL SETTING
4F (9-12) #3. Accelerating electric charges produce electromagnetic waves around them. A great variety of radiations are electromagnetic waves: radio waves, microwaves, radiant heat, visible light, ultraviolet radiation, x rays, and gamma rays. These wavelengths vary from radio waves, the longest, to gamma rays, the shortest. In empty space, all electromagnetic waves move at the same speed?the "speed of light."
G. Forces of Nature
4G (9-12) #5. Magnetic forces are very closely related to electric forces and can be thought of as different aspects of a single electromagnetic force. Moving electric charges produce magnetic forces and moving magnets produce electric forces. The interplay of electric and magnetic forces is the basis for electric motors, generators, and many other modern technologies, including the production of electromagnetic waves.
