【正文】 ng in the same directionfrom one end of the wire to the other. This brings us to the second question .How can free electrons be made to move along a wire? Well ,men have found several ways to do that .One way is chemical. Volta,s voltaic pile,or battery, is a chemical device that makes electricity(or electrons)flow in wires. Another way is magic. Faraday and Henry discovered how mags could be used to make electricity flow in a wire. Mags Almost everyone has seen horseshoe magsso called because they are shaped like horseshoes. Probably you have experimented with a mag, and noticed how it will pick up tacks and nails, or other small iron objects. Men have known about mags for thousands of years. Several thousand years ago, according to legend, a shepherd named Magnes lived on the island of Crete, in the Mediterranean Sea .He had a shepherds crook tipped with iron. One day he found an oddly shaped black stone that stuck to this iron , when many other such stones were found, they were called mags(after Mags).These were natural mags. In recent times men have learned how to make mags out of iron. More important still, they have discovered how to use mags to push electrons through wiresthat is, how to make electricity flow. Before we discuss this, there arecertain characteristics of mags that we should know a piece of glass is laid on top of a horse shoes mag, and if iron filings are then sprink ledon the glass, the filings will arrange themselves into lines. If this same thing is trid with a bar mag(a horseshoe mag straightened out),the lines can be seen more easily. These experiments demonstrate what scientists call magic lines of force. Mags, they explain, work through lines of force that ext end between the two ends of the mag. But electrons seem to have magic lines of force around them, can be proved by sticking a wire through a piece ofcard board, sprinkling iron filings on the cardboard, and connecting a battery to the wire. The filings will tend to form rings around the wire,as a result of the magism of the moving electrons(or electricity).So we can see that there is arelationship between moving electrons and magism, Magism results from the movement of electrons. Of course, electrons are not really flowing in the bar mag, but they are in motion, circling the nuclei of the iron atoms. However, in the mag, circling thelined up in 8 such a way that their electrons are circling in the same direction. Perhaps a good parison might be a great number of boys whirling balls onstrings in a clockwise direction around their heads. —— The Trend Of Integrated Substation Automation Technology Development 指導(dǎo)教師意見(jiàn) 指導(dǎo)教師簽字： 年 月 日
