Extractions: 5 Electromagnetism 5.1 Magnetism So far we have discussed the forces between charges which are at rest with respect to each other. When charges are moving relative to each other they exert an additional force, the magnetic force. This force, as we will see later, plays a negligible role in inter atomic and intermolecular bonding. However, the effect of magnetic fields on atoms and molecules is used widely in all manner of spectroscopies, and we will need to appreciate magnetic behaviour in order to understand the interaction of light and other electromagnetic radiation with atoms and molecules. 5.1.1 The Lorentz Force Magnetic materials were discovered well before the electrostatic effects of rubbing amber. The magnetic iron oxide, magnetite, was mined in Asia Minor well before the birth of Christ, indeed by about 100 BC the Chinese had already discovered that such minerals would align with the north and south poles. By the beginning of the 19th Century it was known that such bar magnets would repel if like poles were facing each other and attract if the poles were of the opposite sense, and the similarities with the behaviour of electric charges had for some time interested scientists of the time. They made the following observations * the force is proportional to the magnitude and sign of the charge on the particle * the force is proportional to the velocity of the charged particle * the force is proportional to the magnitude of the magnetic field * the magnitude of the force depends on the relative orientation between the line of flight and the direction of the magnetic field

New Electromagnetism is evolving into a new science called ethereal (aethereal) mechanics which provides detailed mechanisms for field phenomenon. New Gravity and New Electromagnetism are based on the new law of electromagnetic induction. The new model for electromagnetic induction (New Induction) is superior to Faraday's in every respect and is able to predict things that Faraday can not. From New Induction, arise improved models for the remaining electromagnetic effects that are contained in the paper titled New Electromagnetism. New Electromagnetism reveals a new model for the motional electric law as well as a derivation for magnetic flux velocity. This leads to a practical model for inertia and an improved model for the motional electric law. The paper titled New Gravity extends New Electromagnetism to the modeling gravity. With the new models of electromagnetism, it is possible to derive many of Einstein's postulates of Special Relativity. The new models provide a simple unification of gravity with electromagnetism.

This example has been submitted by the Electromagnetism project at CERFACS [ The electric field at time (where is the time step), is computed using an iterative scheme where tends to . Due to the experimental assumptions, should tend to as k increases. Mathematically, the scheme converges to provided that the spectral radius of A is smaller than 1. This fact holds in exact arithmetic. But in finite precision the scheme diverges. Figure 1 shows that the pseudospectrum spreads out of the unit ball for relatively small matrix perturbations. Figure 2 shows a zoom of the spectral portrait in the neighbourhood of the point z=1 : the contour line which is displayed is the border of the -pseudospectrum of A for .

Extractions: Oersted discovered that a magnetic field is created in the region of a current-carrying conductor. The direction of the magnetic field lines is dependent on the direction of current flow through a conductor. The magnetic field forms a series of concentric circles around a straight conductor. The strength of the magnetic field diminishes inversely as the radial distance from the conductor increases. At any given distance from the conductor, the strength of the magnetic field increases directly with the amount of current in the conductor. Ampere's Rule (right-hand rule) can be used to describe the direction of the magnetic field about a straight conductor. If the conductor is grasped with the right hand in such a way that the right thumb points in the direction of the current, the fingers wrap around the conductor in the direction of the magnetic field. (Some texts refer to the "right-hand rule". Avoid this convention to prevent unnecessary confusion.) The strength of a magnetic field around a conductor can be intensified by coiling the conductor into a loop. A large number of loops form a coil, or

Extractions: When a current-carrying conductor is located in an external magnetic field perpendicular to the conductor, the conductor experiences a force perpendicular to itself and to the external magnetic field. (The Motor Principle) The right-hand rule for force on a conductor can be used to determine the direction of the force experienced on the conductor. If the right thumb points in the direction of the current in the conductor and the fingers of the right hand point in the direction of the external magnetic field, then the force on the conductor is directed outward from the palm of the right hand. The motor principle is used to form a precise definition of the ampere. 1 ampere is the amount of current flowing through two straight parallel conductors 1 metre apart in a vacuum which produces a force of 2 X 10 newtons per metre of conductor. Analog electric meters ( i.e. , galvanometer, ammeter, voltmeter) operate on the motor principle. Electric motors are an important application of the motor principle. An electric motor consists of a permanent external field magnet (stator) and a coiled conducting ammeter (rotor) which is free to rotate within the field magnet. Brushes and a commutator (designed differently if A.C. or D.C. current is supplied to the armature) connect the armature to an external voltage source.

Extractions: Carl J. Wenning, Instructor I. UNIT OVERVIEW A. Unit Plan Summary This unit plan for Electromagnetism is designed for a first-year, high school course in General Physics. A conceptual, as opposed to historical or thematic, teaching approach has been chosen for the instructional material and activities of the unit, although some historical anecdotes, as well as themes such as motors and electric power, will be included. The unit is targeted toward second-semester, first-year physics students with two years of algebra, but no calculus preparation. It has been assumed that the large majority of the students are college-bound juniors or seniors. The textbook, which will be used primarily as a reference source rather than a curriculum guide, is Modern Physics by Frederick E. Trinklein (1990). B. Goals The goals for the unit may be logically grouped into three main categories: content knowledge, process skills, and scientific dispositions. Content knowledge goals specify, in general terms, what students should know and understand at the conclusion of the unit. National education standards are a good source of broad-based goals that provide focal points for the material we will cover in this unit. Content Standard B of the National Science Education Standards (1996), for example, lists two broad goals that are particularly applicable for our purposes. This standard reads as follows:

Extractions: The Delta Science Module (DSM) series has 51 life, physical, and earth science units for grades K-8 that emphasize science concepts, science content, and process skills. The series includes 12 modules for grades 5-6 and 8 modules for grades 6-8. Each requires about 3 to 4 weeks to complete and includes a teacher's guide and materials for a class of 32 students. Teacher's Guide In Electromagnetism, Electromagnetism take 30 to 60 minutes each and can be done by students working individually or in groups. In addition to directions for activities, the teacher's guide provides a module overview, a schedule of activities, objectives for each activity, background information, materials management and preparation tips, sample answers to discussion questions, teaching suggestions, and reinforcement activities. Also included are reproducible activity sheets for student work and a performance-based assessment. A "connections" feature at the end of each activity provides suggestions for extending or applying the concepts addressed. Key to Content Standards: 5-8 (see app. C)

Black Holes And Electromagnetism
Black Holes and electromagnetism. Boris V. Gudiksen Bjørn Østman. Abstract Contents.
http://www.astro.ku.dk/RelViz/ostman/bhe.html

Extractions: Black hole electrodynamics can be very trivial if you consider just a black hole described by the three usual parameters: mass, electric charge and angular momentum. Initially simplifying the case by disregarding rotation, we simply get the well known solution of a point charge. This is of course not physically very interesting, since it seems highly unlikely that any black hole (or any celestial body) should not be rotating. Adding rotation then we have to use the Kerr metric with the change that charge is present. This is the Kerr-Newmann geometry where A rotating charged black hole creates a magnetic field around the hole because the inertial frame is dragged around the hole. Far from the black hole at infinity the black hole electric field is that of a point charge, and the magnetic field is a dipole with magnetic moment
