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.

Electromagnetism: First Principles By Richard Perry rper@cswnet.com First Published 3 / 3 / 2001 - Latest Revision 1 / 17 / 2004 Previous ASCII versions (only) contain a rogue minus sign. Please update any personal copies. Abstract The intent is to present a non-classical insight into the underlying nature of the electromagnetic interaction, a new approach, which will be derived directly from the empirical evidence. What follows is so profoundly disparate from current trends, that unless the reader first shelves everything that he believes to be true about electromagnetic phenomenon, he will fail to grasp the concepts presented, as simple and straightforward as they are. It will be shown that both the electrostatic and magnetostatic interactions are just the vector sum of the dynamic interactions between the quanta of charge in the system, i.e. that the classical electrostatic and magnetostatic forces share a singular source; the motions of quanta of charge relative to one another. Although not originally based upon their work, this paper, in effect, presents a corrected form of the Weber/Guass synthesis, with additions to the model derived from classical premises. Macroscopic Electromagnetic Principles The empirically derived classical equation for the magnetostatic force per unit length, F / L, generated between two infinitely long parallel conductors is commonly stated in the form:

72. Rare-Earth Magnets - Electromagnetism Up, electromagnetism. The discovery of the relationship between magnetism and electricity was, like so many other scientific discoveries http://www.rareearth.org/electromagnetism.htm

Up Electromagnetism The discovery of the relationship between magnetism and electricity was, like so many other scientific discoveries, stumbled upon almost by accident. The Danish physicist Hans Christian Oersted was lecturing one day in 1820 on the possibility of electricity and magnetism being related to one another, and in the process demonstrated it conclusively by experiment in front of his whole class! By passing an electric current through a metal wire suspended above a magnetic compass, Oersted was able to produce a definite motion of the compass needle in response to the current. What began as conjecture at the start of the class session was confirmed as fact at the end. Needless to say, Oersted had to revise his lecture notes for future classes! His serendipitous discovery paved the way for a whole new branch of science: electromagnetics. Detailed experiments showed that the magnetic field produced by an electric current is always oriented perpendicular to the direction of flow. A simple method of showing this relationship is called the left-hand rule . Simply stated, the left-hand rule says that the magnetic flux lines produced by a current-carrying wire will be oriented the same direction as the curled fingers of a person's left hand (in the "hitchhiking" position), with the thumb pointing in the direction of electron flow:

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.

74. Animal Electromagnetism Human beings are not the only creatures on earth that exploit electromagnetism to 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.

Main Page See live article Alphabetical index Electromagnetism Electromagnetism is the physics of the electromagnetic field , including its effect on electrically charged particles The electromagnetic field is a field , encompassing all of space , made up of the electric field and the magnetic field . The electric field is produced by stationary electric charges, and gives rise to the electric force, the force experienced in static electricity ; it is also the force that drives the flow of current in electrical conductors (the phenomenon known as electricity .) The magnetic field is an additional field produced by moving charges, which gives rise to the magnetic force one associates with magnets. While the electric and magnetic forces may sound fairly esoteric, almost all of the phenomena one encounters in daily life (with the exception of gravity ) actually result from electromagnetism. The forces between atoms , including the attractive forces between atoms in a solid that give rise to the rigidity of solids, are predominently electromagnetic, arising from the positive electric charge of the protons in atomic nuclei and the negative electric charge of the electrons surrounding the nuclei. So are the forces acting on the

Electromagnetism The current magnetises the iron core and creates a pair of magnetic poles, one North, and the other South. The two compass needles consequently point in opposite directions. (You may repeat the experiment by clicking on the switch again). This magnetic field would be created whether we had the iron core in the middle or not. But the iron core makes the magnetic field much more powerful. The iron core may be shaped e.g. like a horse shoe, or a C , which is a design used in generators. Generators usually have several North - South pole pairs. For now, let's see how electromagnetism can work "in reverse" on the next page on induction.
