Young Folks' Library, Volume XI (of 20) Wonders of Earth, Sea and Sky By arranging the coil so as to form an electro-magnet, as before described, and holding the magnet under a plate of glass sprinkled with fine iron filings, as shown in Fig. Scientific American Supplement, No. 794, March 21, 1891 If the current is broken, the filings fall from the wire, and only so long as the current flows through the wire does the wire have power to attract iron filings. General Science They represent these curves just as well as iron filings represent magnetic curves, the visible effects in both cases being the consequences of the action of the forces in the places where the effects appear. Experimental Researches in Electricity, Volume 1 He drew men to him as the magnet the iron filings. From Canal Boy to President Or the Boyhood and Manhood of James A.

Burroughs' Encyclopaedia of Astounding Facts and Useful Information, 1889 Next, iron filings are scattered over the surface by means of a small sieve, and, when the curves are well developed,1 the surface is moistened by the aid of an ordinary vaporizer. Scientific American Supplement, No. 470, January 3, 1885 Although such a straight current bearing wire attracts iron filings, its power of attraction is very small; but its magnetic strength can be increased by coiling as in Figure 211. General Science And here is some pulverised iron, or iron filings. The Chemical History of a Candle And if we pass to smaller masses of iron—to iron filings, for example—we find that they act substantially as the needles, arranging themselves in definite forms, in obedience to the magnetic action. Six Lectures on Light Delivered In The United States In 1872-1873 Similarly our minds at best can but indicate magnetic truth, and are distorted by many things that act as iron filings do on the compass. Mince Pie The layer of gum arabic thus becomes softened and holds the iron filings so that the particles cannot change position. Scientific American Supplement, No. 470, January 3, 1885 We saw in Section 296 that a coiled wire through which current was flowing would attract iron filings at the two ends of the helix. General Science The sieve will not do to separate iron filings from copper filings of exactly the same size, but here a magnet will do the business. A Librarian's Open Shelf The experiment with the iron filings introduces a new idea into the mind; the idea, namely, of structural arrangement. Six Lectures on Light Delivered In The United States In 1872-1873 The necessity of holding one's job: what an iron filing that is on the compass card of a man's brain!

On the Nature of Things The point of the needle should barely touch the filings and by slightly agitating the tube the iron filings will separate from the silver and cling to the magnetized needle, as shown. The Boy Mechanic: Volume 1 700 Things for Boys to Do This is the iron filing telephone, which is reversible; for a given magnetic field there is a certain weight of iron filings for maximum intensity. Scientific American Supplement, No. 586, March 26, 1887 In the first place, there was an inexplicable charm about his personality which drew all the common people to him, as iron filings are drawn by a magnet. The Woman's Bible It suffices, after a manner, to materialize the lines of force with iron filings, and to act mechanically upon them, and consequently upon the field itself. Scientific American Supplement, No. 530, February 27, 1886 For instance, the neighbouring colonies found it inconvenient to be in close proximity to Freeland settlements; their population was drawn away by us like iron filings by a magnet.

Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents Thus, if we lay a horse-shoe magnet on a table and sprinkle iron filings round it, they will arrange themselves in curving lines between the poles, as shown in figure 28. The Story of Electricity These lines are very prettily shown by the familiar experiment of placing a sheet of paper over a magnet, and then scattering iron filings on the surface of the paper.

The Day's Work - Volume 1 Lucretius also describes an experiment in which iron filings are made to rise up and "rave" in a brass basin by a magnet held underneath. The Story of Electricity A certain resemblance has been seen between the form of these seeming fibres and that of the lines in which iron filings arrange themselves when sprinkled on paper over a magnet. Side-Lights on Astronomy and Kindred Fields of Popular Science In 1825 Faraday in rectifying naphtha discovered benzole, which by the action of strong nitric acid be converted into nitro-benzole; and this latter, when agitated with water, acetic acid and iron filings produced aniline.

Raphael, looking round on faces dusted over with iron filings, white eyes, greasy blackened clothing, and hairy chests, could have fancied himself transported into the wild nocturnal world of German ballad poetry. The Magic Skin That he believed them to exist at all times round a magnet, and irrespective of the existence of magnetic matter, such as iron filings, external to the magnet, is certain. Faraday as a Discoverer Figure 31 represents the section of a wire carrying a current, with the iron filings arranged in circles round it.
