Increase either or both of these and you get a more powerful electromagnet. Gaseous Dielectrics. — The discussion of the preceding chapters has been largely concerned with the limiting ideal cases of materials that were either perfect conductors in which no electric field could exist or perfect insulators in which there was no net motion of charge. This must equal the electrical work done, which is the product of the charge per mole and the potential difference between the solution and electrode; hence V RT. ~F7 log < (!) where v is the charge per ion or valence and V is the electrode potential.

This particular force, just like the others, plays a crucial role in our existence, but not just that. It has two facets to it without which we still would be in a dark primitive society hunting to kill animals and struggling to live.

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." (3) Oersted's dissertation was heavily influenced by the thought of the German philosopher Immanuel Kant; in fact, in 1798 he served on an editorial staff of a journal largely given over to Kant Microwave Radiometry of Vegetation Canopies (Advances in Global Change Research)

This violates Galilean invariance, a long-standing cornerstone of classical mechanics. One way to reconcile the two theories is to assume the existence of a luminiferous aether through which the light propagates. However, subsequent experimental efforts failed to detect the presence of the aether. After important contributions of Hendrik Lorentz and Henri Poincaré, in 1905, Albert Einstein solved the problem with the introduction of special relativity, which replaces classical kinematics with a new theory of kinematics that is compatible with classical electromagnetism. (For more information, see History of special relativity .) In addition, relativity theory shows that in moving frames of reference a magnetic field transforms to a field with a nonzero electric component and vice versa; thus firmly showing that they are two sides of the same coin, and thus the term "electromagnetism". (For more information, see Classical electromagnetism and special relativity .) In another paper published in that same year, Albert Einstein undermined the very foundations of classical electromagnetism Magnetism, Magnetic Materials download epub

And then they will remember an even earlier report from the Biophysics Lab, of the Aerospace Medical Labs of the Aerospace Medical Div. at Wright Patterson AFB, Ohio dated 1965 entitled, "Personal telemetry transmitter system." When an electric current is passed through the coil it experiences a torque due to the interaction of the current with the magnetic field. As a result the coil pivots and the needle is deflected proportionally to the current passing through the coil. The unit of electric current, ampere, is called after Andr�-Marie Amp�re.

Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet. The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding , source: College Physics: Electricity and Magnetism, Light, and Atomic Physics (3rd ed.)
