After Oersted's 1820 discovery that electric currents create magnetism, it was obvious that in some way magnetism should be able to create electric currents. The discovery of electromagnetic induction, in 1831, by Michael Faraday and Joseph Henry was one of the most important of the 19th century, not only scientifically, but also technologically, because it is the means
Electromagnetic induction makes it easy and natural to generate alternating current. Use of transformers makes it practical to distribute ac over long distances. Although Nikola Tesla understood all this, Thomas Edison chose not to, and thereby hangs a tale. Alternating current circuits obey a differential equation identical to the harmonic oscillator resonance equation
How Does a Solenoid Work?
A solenoid works by having electricity flow through its copper
wire that is provided by a power supply and a switch. Learn how a
solenoid becomes a magnet when electricity is supplied to it with
information from a science teacher in this video.
What Is an Electrical Inverter?
An electrical inverter is a device that can create an alternating
current from a direct current, allowing the current to go backwards and forwards instead of in only one direction. Find out how an electrical inverter works from a science teacher in this

Plaque Formation On Arterial Wall
3-D animation showing how plaque builds up on the wall of the artery, narrowing the vessel. Very short and no sound, but excellent illustration. Grades 6-12. 15 sec.
Video clip shows a microscopic blood vessel only one cell layer thick, so that individual blood cells must move through single file. Grades 5-12. 13 seconds.
Short video clip shows how a vein contains one-way valves that work in conjunction with skeleto-muscles. When the sceleto-mucles contract, the valve open and blood is forced toward the heart. When the sceleto-muscle relaxed, the valve closed to prevent the backflow of blood away from the heart. Grades 5-12. 19 sec.
