electro ballistic (olektrobalistik)

Concerned with electricity as used to determine the velocity of a projectile at any part of its flight: an epithet applied to various instruments invented by Nauvez. The projectile pa es in succe ion through two or more screens, the distances between which are known; and, the exact time of pa age through each screen being electrically recorded, a simple calculation gives the velocity at that part of the flight. electrodeposit (ē-lektro-de-poz'it), v. t.

IMG:content-0295.jpg:[merged small][graphic][merged small][merged small][merged small] electromagnet of soft iron and a current of electricity is pa ed through it, the bar becomes a temporary magnet with a north and a south pole; the end at which the current circulates through the wire in the direction of the hands of a clock, as the observer looks at it, is the south pole. In practice, an electromagnet has ordinarily a horseshoe form. It consists of two cylinders, or cores, of soft iron, fastened together at one end and each wound many times with insulated wire; the wire must be so wound that if the horseshoe were straightened the direction of winding would be the same throughout. An electromagnet may be made very powerful, so as to support a ton or more. The soft iron core retains its maximum magnetization only so long as the current is pa ing, and loses nearly all of it the instant the current ceases. This principle is made use of in the telegraph (which see), electric clocks, electric call bells, etc. If the core is made of steel, it becomes under the action of the current a permanent magnet. electromagnetic (ē-lektro-mag-net'ik), а. Pertaining to electro magnetics, or to the relation between electricity and magnetism; of the 1870 above or within this, if the cylindrical form is used, a flat needle of aluminium is hung by a delicate wire. The needle is kept in a constant electrical condition by connection usually with a Leyden jar placed above or below, and if the two pairs of quadrants are di imilarly electrified - that is, are in a state of different potential, as by connecting them respectively with the poles of a voltaic cell-the needle is deflected from its position of rest, and the amount of this deflection, as measured by the motion of a spot of light reflected from a small mirror attached to it, gives a means of calculating the difference of potential of the bodies under experiment. In another method of using the quadrant electrometer the pairs of quadrants are kept at a constant difference of potential, while that of the needle varies. Arranged in this manner, it is much used in the investigation of atmospheric electricity. Lippmann and Dewar have devised very delicate capillary electrometers, based on the alteration of the force of capillarity by electric action.
