Electromagnetism Home Electromagnetic Inertia Have you ever thought “If an electron induces a magnetic field when it moves, and magnetic fields contains energy, where does the energy to create this field come from?” Click here to find out more about Electromagnetic Inertia. Electrostatic Potential Energy The starting point for all electrostatic interactions is that between two point electric charges such as two electrons, or between a positron and an electron. In the 19th century scientists did not understand the interaction, and invented the concept of “potential energy” to provide the force that drove these particles together or apart. It was only when Einstein developed the equivalence of mass and energy that the true source of the energy became apparent. You are probably familiar with the concept that electric fields contain energy and it is the interaction between the fields of the two charges that leads to changes in their energy and hence to the forces between them, energy being simply the integral of force over distance. This paper develops the equations for the interaction at any point in space near the charges, without recourse to “potential energy”.

Building an electric motor in 10 minutes. The single brush motor. A bigger motor. The double brush improvement. ... A railgun in 10 minutes A motor in 10 minutes Back in the 1960's my father taught me how to make the little electric motor we will make here. Sometime in the 1980's I saw a description of it in the magazine "Physics Teacher". Lately I have seen it described as Beakman's motor, after the science oriented TV show on which it recently appeared. The motor is simply a battery, a magnet, and a small coil of wire you make yourself. There is a secret to making it (which I will of course share with you) which is at the same time clever and delightfully simple. What you will need: A battery holder, such as Radio Shack #270-402 (holds a "C" cell) or #270-403 (holds a "D" cell). A battery to fit the holder. A magnet such as Radio Shack #64-1877, #64-1895, #64-1883, #64-1879, or #64-1888. Some magnet wire such as Radio Shack #278-1345. We want enamel coated 22 gauge (or thicker) wire. We will only need about a yard of wire, so the Radio Shack package will make a dozen motors or more. Some heavier wire such as Radio Shack #278-1217 or #278-1216. We want bare wire of 18 or 20 gauge, so we will be removing the plastic insulation from the wires listed above. We will need less than a foot of this wire per motor.

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?

10. Oersted Episodes in Romantic Science Oersted and the Discovery of electromagnetism by Frederick Gregory. Department of History University of Florida. http://www.clas.ufl.edu/users/fgregory/oersted.htm

Episodes in Romantic Science Oersted and the Discovery of Electromagnetism by Frederick Gregory Department of History University of Florida Contemporary historians of science do not all agree that the discovery of electromagnetism by Hans Christian Oersted in 1820 was directly tied to Friedrich Schelling's system of romantic nature philosophy, nor is it clear how one could establish this assertion beyond doubt. What is clear is that Oersted was attracted to certain fundamental tenets of German idealistic thought and, as we shall see, a direct personal link between Schelling and Oersted can be demonstrated. In fact, it was reported later in the nineteenth century that a few years before his death Oersted himself credited Schelling with the stimulus necessary to the discovery of electromagnetism. The reader may not have anticipated that thoughts as abstruse and apparently "unscientific" as Schelling's could constitute an intellectual environment that might contribute to the uncovering of so fundamental a scientific discovery as electromagnetism. Hans Christian Oersted Hans Christian Oersted was born in the south central part of Denmark in 1777. He and his younger brother Anders entered the University of Copenhagen in 1793, Hans concentrating on medicine, physics, and astronomy while Anders took up law. The brothers did not confine their attention to these fields, for, as was common in a university education in those days, they dabbled in a wide variety of disciplinary studies. In 1797 Hans earned first prize for an essay on "Limits of Poetry and Prose." In the same year the elder Oersted brother completed a degree in pharmacy with high honors, and two years later he was awarded the degree Doctor of Philosophy with a dissertation entitled "On the Form of an Elementary Metaphysics of External Nature."

Welcome to the NASA Breakthrough Propulsion Physics (BPP) Project Public Information Site To see more BPP artwork click on the picture ABOUT BPP NASA supported the Breakthrough Propulsion Physics Project from 1996-2002 to seek the ultimate breakthroughs in space transportation: (1) propulsion that requires no propellant mass, (2) propulsion that attains the maximum transit speeds physically possible, and (3) breakthrough methods of energy production to power such devices. Topics of interest include experiments and theories regarding the coupling of gravity and electromagnetism, the quantum vacuum, hyper fast travel, and super luminal quantum effects. Because the propulsion goals are presumably far from fruition, a special emphasis is to identify affordable, near-term, and credible research that could make measurable progress toward these propulsion goals. This web site describes the methods and activities of the Breakthrough Propulsion Physics Project.

Hermann Klaus Hugo Weyl Born: 9 Nov 1885 in Elmshorn (near Hamburg), Germany Died: Click the picture above to see eight larger pictures Show birthplace location Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Main index Hermann Weyl Hilbert . After submitting a doctoral dissertation He attempted to incorporate electromagnetism into the geometric formalism of general relativity. Weyl published (1913) which united analysis, geometry and topology . He produced the first guage theory in which the Maxwell electromagnetic field and the gravitational field appear as geometrical properties of space-time. From 1923-38 he evolved the concept of continuous groups using matrix representations . With his application of group theory to quantum mechanics he set up the modern subject. He also made contributions on the uniform distribution of numbers modulo 1 which are fundamental in analytic number theory More recently attempts to incorporate electromagnetism into general relativity have been made by John Wheeler, Kaluza and others. These theories, like Weyl's, lack the connection with quantum phenomena that is so important for interactions other than gravitation.
