Creating Electromagnetism by Ron Kurtus (revised 9 August 2002) By wrapping an insulated strand of wire around a piece of iron or steel and running electrical current through the wire, the metal can become magnetized. This is called an electromagnet. A magnetic field is created around a wire when it has electrical current running through it, and creating a coil of wire concentrates the field. Wrapping the wire around an iron core greatly increases the strength of the magnetic field. Questions you may have include: How can you make an electromagnet? What factors are involved in electromagnetism? How does an iron core affect the strength?

Next: Review Sheet Up: No Title Previous: Homework Assignments History A Ridiculously Brief History of Electricity and Magnetism Mostly from E. T. Whittaker's A History of the Theories of Aether and Electricity... 900 BC - Magnus, a Greek shepherd, walks across a field of black stones which pull the iron nails out of his sandals and the iron tip from his shepherd's staff (authenticity not guaranteed). This region becomes known as Magnesia. 600 BC - Thales of Miletos rubs amber ( elektron in Greek) with cat fur and picks up bits of feathers. 1269 - Petrus Peregrinus of Picardy, Italy, discovers that natural spherical magnets (lodestones) align needles with lines of longitude pointing between two pole positions on the stone. 1600 - William Gilbert, court physician to Queen Elizabeth, discovers that the earth is a giant magnet just like one of the stones of Peregrinus, explaining how compasses work. He also discusses static electricity and invents an electric fluid which is liberated by rubbing. ca. 1620 - Niccolo Cabeo discovers that electricity can be repulsive as well as attractive.

What Holds it Together? Electromagnetism The electromagnetic force causes like-charged things to repel and oppositely-charged things to attract. Many everyday forces, such as friction, and even magnetism, are caused by the electromagnetic, or E-M force. For instance, the force that keeps you from falling through the floor is the electromagnetic force which causes the atoms making up the matter in your feet and the floor to resist being displaced. The carrier particle of the electromagnetic force is the photon ). Photons of different energies span the electromagnetic spectrum of x rays, visible light, radio waves, and so forth. Photons have zero mass, as far as we know, and always travel at the "speed of light", c, which is about 300,000,000 meters per second, or 186,000 miles per second, in a vacuum.

James Clerk Maxwell The Scottish physicist James Clerk Maxwell, b. Nov. 13, 1831, d. Nov. 5, 1879, did revolutionary work in electromagnetism and the kinetic theory of gases. After graduating (1854) with a degree in mathematics from Trinity College, Cambridge, he held professorships at Marischal College in Aberdeen (1856) and King's College in London (1860) and became the first Cavendish Professor of Physics at Cambridge in 1871. Maxwell's most important achievement was his extension and mathematical formulation of Michael Faraday's theories of electricity and magnetic lines of force. In his research, conducted between 1864 and 1873, Maxwell showed that a few relatively simple mathematical equations could express the behavior of electric and magnetic fields and their interrelated nature; that is, an oscillating electric charge produces an electromagnetic field. These four partial differential equations first appeared in fully developed form in Electricity and Magnetism (1873). Since known as Maxwell's equations they are one of the great achievements of 19th-century physics. Maxwell also calculated that the speed of propagation of an electromagnetic field is approximately that of the speed of light. He proposed that the phenomenon of light is therefore an electromagnetic phenomenon. Because charges can oscillate with any frequency, Maxwell concluded that visible light forms only a small part of the entire spectrum of possible electromagnetic radiation.

It assumes a basic knowledge of electromagnetic induction. Contents Equipment required Experiment Setup Experiment Results Questions ... Further experiments Equipment required :- Bicycle dynamo A Pico PC based oscilloscope (We used a single channel ADC-40 Connecting cable Any bicycle dynamo should be suitable for these experiments. We used a bicycle dynamo with a pulley wheel, handle and bulb mounted on a demonstration stand. This was purchased from Griffin Education (part number XKE-650-J). Experiment setup The experiment was setup as shown in the photograph below. Experiment Results To test the setup, the handle on pulley was given a single turn. PicoScope oscilloscope software was set to single shot trigger to capture the results. Pre-trigger (20%) was used to show signals before and after the trigger event. The PicoScope screen shot shows the results: Questions 1. How long did the dynamo keep turning?

59. Animal Electromagnetism Human beings are not the only creatures on earth that exploit electromagnetismto sense their surroundings and communicate with one another. http://www.spectrum.ieee.org/publicaccess/9603teaser/9603fish.html

The Strange Senses of Other Species by Ingrid Wickelgren Contributing Editor H uman beings are not the only creatures on earth that exploit electromagnetism to sense their surroundings and communicate with one another. A variety of fresh-water fish from rivers in Africa and South America do so as well. What is more, they do it in quite a sophisticated fashion. F or example, unless the number of species in a particular river makes it too difficult, they seem to obey a sort of master frequency allocation plan, with each species assigned to a different band, and individuals using different frequencies within that band. If two fish approach each other and find that their signals are too similar, one will shift its frequency in a behavior known as the jamming avoidance response. Thanks to the research of the late Walter Heiligenberg and his group at the Scripps Institution of Oceanography in San Diego, Calif., the jamming avoidance response is probably the best understood vertebrate behavior in terms of the neural circuitry and information processing involved. I nterestingly, weakly electric fish do not use some sort of analog of radar or sonar, as bats do. Rather, they establish a more or less dipole field around themselves and sense the resulting voltage distribution across their skin surface. Perturbations in the field cause corresponding perturbations in the potential distribution, which the fish analyze to learn about the environment.
