The electron is a fundamental subatomic particle that carries a negative electric charge. It is a spin-½ lepton that participates in electromagnetic interactions‚ and its mass is less than one thousandth of that of the smallest atom. Its electric charge is defined by convention to be negative‚ with a value of −1 in atomic units. Together with atomic nuclei‚ electrons make up atoms; their interaction with adjacent nuclei is the main cause of chemical bonding. The name "electron" comes from

How to Make a Simple Electric Motor Energy comes in many forms. Electric energy can be converted into useful work‚ or mechanical energy‚ by machines called electric motors. Electric motors work due to electromagnetic interactions: the interaction ofcurrent (the flow of electrons) and a magnetic field. Problem Find out how to make a simple electric motor. Materials Needed D battery Insulated 22G wire 2 large-eyed‚ long‚ metal sewing needles (the eyes must be large enough to fit the wire through)

The History of the Electric Guitar The desire to increase the sound of the guitar existed long before the development of electrical amplifiers and speakers. Musical performances in the 19th century were characterized by ever-larger concert settings and ensembles. Musicians needed louder and more powerful instruments‚ which became possible by using new materials and designs. The introduction of steel strings in the 19th century meant not only greater volume‚ but greater tension on instruments

1.The competition to develop and market electric vehicles has increased during the last year and is expected to continue to increase. The electric bicycle industry has four major manufacturers and a large group of small companies. The major manufacturers are Honda‚ Suzuki‚ Sanyo and Yamaha. They mainly sell products to Japan and Europe. The other group of manufacturers is much smaller in size and sales volume. These manufacturers have products they sell into the U.S.‚ European and Asian markets.
