means of a principle discovered independently by two physicists in 1831 - Michael Faraday of England and Joseph Henry of the United States. Faraday and Henry found that they could produce electricity in a coil of copper wire by moving the coil near a magnet. This process is called electromagnetic induction. A simple generator (see Figure 1 below) consists of a single loop of wire turning in a magnetic field. Electricity is produced only while the loop is rotating. As the loop rotates‚ the two sides

1 a little UML UML for the Java Associate Oh my! Umm‚ hey‚ I‛m really not ready yet‚ OK? UML is Cool. Rumor has it there are some UML questions on Sun’s new Java Associates exam. Sadly‚ the new Head First book on OO isn’t quite ready yet (be sure to check hfoobook.com toward the end of 2005!)‚ but we’ve taken a few random pages (and parts of pages) from it and put them together here. So‚ if you don’t mind the lack of organization‚ you should find everything you need to know about UML

field‚ scientists began to search for the converse phenomenon from about 1821 onwards. The problem they put to themselves was how to ‘convert’ magnetism into electricity. It is recorded that Michael Faraday* was in the habit of walking about with magnets in his pockets so as to constantly remind him of the problem. After nine years of continuous research and experimentation‚ he succeeded in producing electricity by ‘converting magnetism’. In 1831‚ he formulated

will too much‚ or too little‚ humidity do to a computer? When considering HVAC‚ what is the difference between a positive pressure system and a negative pressure system? What causes EMI and what can be done to prevent problems with it? How can a magnet affect a floppy disk or tape? What types of materials can you use to clean internal PC components? When is it important to use an anti-static vacuum? How are backups related to preventive maintenance? What is the difference between a surge

Separation Challenge Problem: Salt‚ sand‚ wood chips‚ iron filings Materials Needed: a magnet‚ water‚ a pot‚ clean flat surfaces‚ a burner‚ filter paper‚ a stirrer‚ and four beakers for each item in the mixture Plan Brainstorm: Separate the items one by one using their different properties. Final Plan: To separate sand‚ salt‚ wood chips and iron filings First‚ use a magnet to remove the iron. Since some sand/salt will get caught with the iron filings‚ you may have to spread out the separated
