It is a practical hands-on trainer where the elements in the system are presented on an open board in a clear and logical manner. Individual circuit elements are studied and can then be interconnected to develop more complex circuits. Inductance is studied using a test rig comprising two coils wound side by side on a former. Different core materials can be used with the former allowing their performance in magnetic circuits to be evaluated. Using soft iron core parts it is possible to form different arrangements of magnetic circuit to investigate magnetic coupling between primary and secondary windings. Magnetic material performance is investigated at different supply frequencies. A small conventional transformer is fitted to the board to allow basic performance and ratio experiments to be carried out.

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

Waveguides Electromagnetism is the physics of the electromagnetic field : a field , encompassing all of space, composed 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 magnetic field is a field produced by the motion of electric charges, giving rise to the magnetic force one associates with magnets . The term "electromagnetism" comes from the fact that the electric and magnetic fields are closely intertwined, and, under many circumstances, it is impossible to consider the two separately. For instance, a changing magnetic field gives rise to an electric field; this is the phenomenon of electromagnetic induction , which underlies the operation of electrical generators induction motors , and transformers The term electrodynamics is sometimes used to refer to the combination of electromagnetism with mechanics . This subject deals with the effects of the electromagnetic field on the mechanical behavior of electrically charged particles.

117. Electromagnetism electromagnetism Probability Waves Quantum Mechanics. electromagnetism.The constituents of atoms comprise small massive entities held together by http://www.lancs.ac.uk/depts/physics/vibrations/vib13.htm

Preface Electromagnetism The constituents of atoms comprise small massive entities held together by forces much stronger than that due to their gravitational attraction. It is however not difficult to knock a few of these constituents apart (e.g. by simply combing ones hair with a plastic comb on a dry day) and to observe that they can both attract and repel one another. This interaction is called the force due to electricity and the constituents are said to possess electric charge. The precise nature of the force between charged particles depends on their state of relative motion. Charges in motion are called electric currents and the forces between moving charges are referred to as electromagnetic. The simple bar magnet owes many of its properties to the motion of charges in its interior. The fact that electric charges can influence other charges across space is the fundamental reason that electrical forces can be harnessed as a source of usable power. It was Michael Faraday who conceived of the idea that such forces might be mediated by an entity in the space between the charges and that it could exist in its own right. This idea gave rise to the concept of the electromagnetic field. Just as the forces of sound are transmitted via the medium of air so the forces of electromagnetism are transmitted via the electromagnetic field. However unlike air the energy and momentum of the field is not associated with material particles like the molecules of the air.

Relativity and Electromagnetism, 16 Lectures, HT by Dr L.J.Mason Aims Maxwell's electromagnetic theory revealed light as an electromagnetic phenomenon. Its speed proved to be observer independent, a discovery which led to the overthrow of classical Newtonian mechanics, in which time was absolute. The aim of the course is to study Einstein's Special Theory of Relativity and Maxwell's electrodynamics, which have necessitated profound changes in our ideas of space and time. These theories together with Quantum Theory are essential for an understanding of modern physics. Synopsis Introduction to Maxwell's electromagnetic equations. Constancy of the speed of light.

Home TaSS HOME ... - The Earth's Magnetosphere Electromagnetism In the late 1700s and early 1800s many scientists and philosophers believed that all forces of nature had the same source. This was especially easy to believe about electricity (see Electricity ) and magnetism (see Magnetism ). Both phenomena seemed to have two kinds of something - a positive and a negative charge or a north and a south pole. In addition, like charges and poles repel and unlike charges and poles attract. It was noted that compass needles could be affected by lightening strikes and Benjamin Franklin had reported that he had magnetized needles with a stored electric current. However, no firm evidence existed that linked electricity and magnetism until Hans Christian Oersted performed a critical experiment during a lecture in 1820. It is unclear whether this was an accident or a carefully constructed experiment. Oersted himself had believed that electricity and magnetism were linked for at least 12 years. Whatever his intent, he placed a wire above the compass needle and connected both ends across a battery and the needle spun until it was at right angles to the wire. In further experiments, using instruments similar to the one pictured below, he was able to determine that the magnetic influence surrounded the wire in a circle.

Black Holes and Electromagnetism Abstract: Contents Black Hole Electrodynamics Accretion Disks Black Hole Magnetosphere Flux Freezing ... Disc Field Lines Black Hole Electrodynamics Black hole electrodynamics is the theory of electrodynamics outside a black hole. This is evident since we cannot gain information about anything inside the event horizon (i.e. 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 However, black holes do not even have charges. The ratio of charge to mass, Q/M, cannot exceed
