What Holds it Together? Electromagnetism The electromagnetic force causes like-charged things to repel and oppositely-charged things to attract. Many everyday forces, such as friction, and even magnetism, are caused by the electromagnetic, or E-M force. For instance, the force that keeps you from falling through the floor is the electromagnetic force which causes the atoms making up the matter in your feet and the floor to resist being displaced. The carrier particle of the electromagnetic force is the photon ). Photons of different energies span the electromagnetic spectrum of x rays, visible light, radio waves, and so forth. Photons have zero mass, as far as we know, and always travel at the "speed of light", c, which is about 300,000,000 meters per second, or 186,000 miles per second, in a vacuum.

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.

Electromagnetism and Charge Mass is one attribute of matter. It is associated with the gravitational force Charge is another attribute of matter. It is associated with the electromagnetic force The theory of electromagnetism was first proposed by James C. Maxwell: Light is an electromagnetic wave. Matter can be electrically charged. A stationary charge has an electric field. A moving charge can produce a magnetic field. Just as gravity accelerates masses, electric and magnetic fields can accelerate charges. When accelerated, charges give off ( emit electromagnetic radiation

The Joseph Henry Papers Project is documenting the life of Joseph Henry (1797-1878), the most revered American scientist of his times and the first Secretary (director) of the Smithsonian Institution. Henry's pioneering work in electricity and magnetism helped bring about the invention of the telegraph , the electric motor , and the telephone . At the Smithsonian Institution he created the outlines of the unique research and cultural institution that we know today. "The most prominent idea in my mind is that of stimulating the talent of our country to original research,in which it has been most lamentably difficient [sic]to pour fresh material on the apex of the pyramid of science, and thus to enlarge its base."Joseph Henry, on the purpose of the Smithsonian Institution.

Electromagnetism Introduction: So many devices and equipment around us are using electromagnetism as their driving force. Electric bells, buzzers, telephones, speakers, radios, and electric motors used in fans, hair dryers, vacuum cleaners and any other device that you can imagine are all using electromagnets. This project is an opportunity to learn more about electromagnets and find out what factors affect the strength of an electromagnet. Material and instructions: If you select electromagnetism as your project, you will have a large variety of choices for your experiment and display. For example you can make a simple electromagnet, make an electric catapult, take pictures of a magnetic field or make any other device that uses an electromagnet. Your display can include a drawing of your experiment and a working model that works and everyone can test. Materials needed for this project can be found at home or purchased locally. Most Electromagnet kits also have the necessary materials and step by step instructions on how to make any of the above subjects. Depending on how complete your kit is, you may need to purchase or gather some additional items to complete your project. You may

Electromagnetism and magnetism Interaction between a magnet and a conductor through which flows a current The thermal and chemical effects of an electric current occur in the track of the current . Consider next actions of currents away from it . Just as electricity at rest has its electric field, so does the moving one; the environment of a conductor carrying a current exercises apparent distant action: Especially on nearby magnetic needles. A magnetic needle has at every point on Earth's surface a definite direction (in a definite magnetic meridian ) and, if you force it to turn elsewhere and then release it, it will always return to its initial direction. Apparently a force ( Earth's magnetism ) keeps the needle within the magnetic meridian; it requires work, to deflect it from it. Work of this kind can be performed by an electric current: It diverts the magnetic needle (first discovered by Oerstedt 1820) and thereby performs what only a magnet can do - in other words: Flowing electricity exerts magnetic forces . For the direction in which the current turns the needle you have the rule: Imagine you swim in the conductor
