This last wire runs throufih a pieie of porcelain, nuea Of other nonconducting material. "P." so as to bO Insulated from tho portion of the plug screwed Into the cylinder, the j othet end having a screw by which the wire carrying the current can be fast -ened to It. If now- we connect a wire to the cylinder cyl-inder and another to the screw, above mentioned, and then send a current of electricity under a high pressure through thts wire, the current will go through the porcelain insulated wire until it conies to the 1-64-inch or l-3C-inch air space and then burst or Jump across this space, giving a spark as it does soft so-ft will then go through the iron of the cylinders to the wire which is connected to them at some distant point. The pressure or voltage required to cause the current to break through, or trical devices notably, the electric balL the telegraph, electric lifting magnets, etc. 3. As a soft Iron core Incomes a magnet, mag-net, as stated above. Whan cunent flow through t he coll. so also can a current be made to flow through the wire of the coll. if the core is msdr to be a magnet, or. In other words, is magnetized. mag-netized. This action, you will note. Is simply the reverse action of tho one explained aboj Let us aee what affects the strength of the magnetism of the core. 4. If we had but one turn of m ire about the core, when tho current of a certain voltage and a certain amperagc l sent through the wire, the core will be magnetised lo a certain amount; If we had two turns, it will be twice the amount, hih! if three turns, three times the amount. Thus tiie strength of the magnetism is dlrectlv dependent on the number of turns of w ire and the amount of current flowing through the wirv Now, let ua see what will affect the strength of the current which will flow-through flow-through the w ire In the second case-that case-that la. where it is made to flow by the magnetizing of the core. 5. If there be but one turn of wire around this core, when it Is macnt'zed to a certain extent, a current ha vine a certain amount of voltage and amperage will flow, while if there be but two turns ahont the core, each turn will have the same voltage, and so. likewise, three will clve us three times the voltage, and ln.Aoo turns. lO.OOO times tiie voltage of j one turn. 6. The amount of current mad to flow will, however, de. Tease as the number num-ber of turns is decreased, or. in other words, the amperes, when there are 1ft.-ftM 1ft.-ftM turn? of wire, will be one-ten thousandth thou-sandth of what it will he with one turn of wire. There is one difference between the 3 etfdn when the core becomes magnetized magne-tized by em-rent passing through the wire, and the reverse case, that Is. where the citrrent Is made to flow through tiie wire due to the magnetizing of the core which is this: 7. Tn the rase of t-h" core boin? mac-netized mac-netized by a current flowing through the roll, the core w-ill become a maenet the moment the eijrrent flows and will re-main re-main a magnet ju.t as long as it doee flow, losing its magnetism only when the current stops flowing or is interrupted. inter-rupted. S. In the second ease, however, tha t is, where the current iff made to flow through the wire due to the magnetizing of the core, there will be a shot of current cur-rent the instant the core is magnetized, or the instant It is demagnetized, but the current will not flow in n constant stream. It stopping after the instant of magnetism, even though the core remains a reagnct. Tf the core be suddenly demagnetized, there will again ho a shot of current through the wire, of the same voltage as when the core is magnetized, but It will flow in the opposite direction. Every magnet has what is known as a north pole and a south pole. Tf suspended sus-pended from a string, the north pole will always point towaiid the north and the south pole toward the south. T must tell yon of a little experiment by whleh It can be proven that there are Invisible lines of power radiating from the magnet, which lines are called magnetic mag-netic lines of force. Tf we lfld a bar magnet on the table, and placed a sheet of stiff paper over it, and then sprinkled some iron filings on the paper, these filings, upon tanning the paper. Would instantly taVe definite lines on the paper, much as shown In the illustration. il-lustration. Fine as the filings may be. thev have a certain amount of weight, and so there must be some Invisible force, acting act-ing even through the na per, to a rrange the filings In this definite form. The number of lines formed, and other tests, prove that the power of the magnet Is ma.lc up. not of a single force, but of a great many forces which act In a definite defi-nite way or in definite lines, thus proving prov-ing that there are the magnetic lines of force ment toned above. Note how the lines arrange themselves In sort of semicircles running from one pole to the other. |
