Movie Gallery How A Metal Detector Works The operation of metal detectors is based upon the principles of electromagnetic induction. Metal detectors contain one or more inductor coils that are used to interact with metallic elements on the ground. The single-coil detector illustrated below is a simplified version of one used in a real metal detector.

A pulsing current is applied to the coil, which then induces a magnetic field shown in blue. When the magnetic field of the coil moves across metal, such as the coin in this illustration, the field induces electric currents (called eddy currents) in the coin. The eddy currents induce their own magnetic field, shown in red, which generates an opposite current in the coil, which induces a signal indicating the presence of metal. Questions or comments?

Movie Gallery Faraday's Magnetic Field Induction Experiment When Michael Faraday made his discovery of electromagnetic induction in 1831, he hypothesized that a changing magnetic field is necessary to induce a current in a nearby circuit. To test his hypothesis he made a coil by wrapping a paper cylinder with wire. He connected the coil to a galvanometer, and then moved a magnet back and forth inside the cylinder.

Please install this software in order to view our interactive Java tutorials. You may download the necessary software by clicking on the "Get It Now" button below. Click and drag the magnet back and forth inside the coil. When you move the magnet back and forth, notice that the galvanometer needle moves, indicating that a current is induced in the coil. Notice also that the needle immediately returns to zero when the magnet is not moving. Faraday confirmed that a moving magnetic field is necessary in order for electromagnetic induction to occur.

83. Electromagnetic Induction And Inertia Derivation and proof of the inertial properties of electrostatic and magnetostatic fields. http://www.mariner.connectfree.co.uk/html/e_m_inertia.html

Electromagnetic inertia Home EM Overview Have you ever thought “If an electron induces a magnetic field when it moves, and magnetic fields contain energy, where does the energy to create this field come from?” It comes from the force that accelerated the electron from rest - the work done in accelerating it (as the integral of the force over the distance) directly creates the energy of the induced field. Another way of saying this is that part of the electron’s inertia comes from supplying energy to the induced magnetic field. We do not know the fine detail of the electron’s electric field structure, only the way it falls off as the square of the distance when we are some way away from the electron (in terms of the electron size). So it is easier to deal with the inertia of simple electromagnetic fields. The equations are straightforward and derived for Newtonian velocities, using source equations to be found in any first-year physics textbook. Electrostatic inertia - the basics If a point in space has a vector electrostatic field of strength X ’ volts/meter, its energy density over space ‘dE

85. PowerLabs NEW Rail Gun! Electromagnetic capacitor powered 20kJ rail gun research. http://www.powerlabs.org/railgun2.htm

PowerLabs Rail Gun 2.0 Research! RailGuns are expensive ! This project was made possible by the generous contributions of my sponsors. Would you like to sponsor PowerLabs research? Please donate *any* amount. Every little bit helps and you can be sure your money will be put to good use :-) Project Introduction: From its conception, the original PowerLabs Linear Magnetic Accelerator ("Rail Gun" , or "Railgun" ) was conceived for the primary goal of simply proving that it could be done; on a low budget, with common materials and powered by a never tried before electrolytic capacitor bank In that, it was extremely successful: Not only did the gun fire flawlessly over 30 times (it is not uncommon for research rail guns to break down in the first shot), but it also attracted vastly more attention than I could ever have hoped for: After its page generated hundreds of thousands of hits, the gun was featured on Discovery Channel The original railgun design was completely experimental; built, assembled and operated solely by myself, on my first year of engineering school and being entirely based on my knowledge of electricity and magnetism at the time. With the catastrophic failure of the injector casing and the injector/rail assembly during a full power shot, I found the extra motivation I needed to re-design the gun so that my research in this area could continue. Of course, by now, with 3 years of engineering school and extensive research on the subject, I expected even greater successes.

BRIGHAM YOUNG UNIVERSITY Search BYU Contact Help ECEn Home Forms Differential Forms in Electromagnetic Theory Brigham Young University Department of Electrical and Computer Engineering 459 Clyde Building, Provo, Utah 84602 Richard H. Selfridge David V. Arnold and Karl F. Warnick The differential forms research group at BYU is investigating the use of the calculus of differential forms in teaching and research. Differential forms have been used to express Maxwell's laws since early in this century, but many of the advantages of forms as a tool for applied electromagnetics have only recently been discovered. Relative to the usual vector analysis treatment, differential forms make elementary electromagnetics clearer, simpler, and more intuitive. At the same time, differential forms are a powerful tool for research, and open the way for the application of powerful tools of modern differential geometry to electromagnetics. The purpose of this website is to make available publications and course materials to those interested in differential forms and their use in research and teaching. Download the latest EM theory course notes , also available in pdf form I have recently published a new book on electromagnetics using differential forms with problems and solutions: K.

ANTENNA.EXE ANTENNA.EXE is a self unzipping DOS file containing WIRE, based on some of the original MiniNEC work. However, the changes were so drastic that it can no longer referred to it as a variation on MiniNEC. One feature that it has is that it can handle coaxial structures. Thus a coax can be analyzed as two wires of different radii. There is care required at the terminations since there is fringing capacitance since an actual end-cap has not been included. A paper covering the theory behind WIRE is also available for download. The plotting of current and patterns were designed to be rather straight forward. The package can handle up to about 160 unknowns in DOS. program and documentation provided by author Dr. William A. Davis mininec3.zip
