Natural Magnet. A loadstone.
Needle. A term applied to a bar-magnet poised horizontally upon a vertical point.
A magnetic needle, or the magnet in a mariner’s compass.
Negative. Opposed to positive.
Negative Electricity. The kind of electricity with which a piece of amber is charged by friction with flannel.
In a galvanic battery or cell the surface of the zinc is charged with negative electricity. Negative electricity, according to the theory of some scientists, really means a deficiency of electricity.
Negative Electrode. The same as Negative Element.
Negative Element. The plate not dissolved by the solution in a voltaic cell; the one which is positively charged.
The carbon, platinum, or copper plate or pole in a battery.
Negative Feeder. The conductor which connects the negative mains with the negative poles of a generator.
Negative Plate. (See [Plate, Negative].)
Negative Pole. (See [Pole, Negative].)
Neutral Feeder. The same as Neutral Wire.
Neutral Wire. The central wire in a three-wire system.
Nickel-bath. A bath for the electro-deposition of nickel.
Non-arcing Fuse. A fuse-wire which is enclosed in a tube packed with asbestos or silk, and which does not produce an arc when it fuses or blows out. It is practically noiseless, save for a slight hissing sound, accompanied by a light puff of smoke, which escapes from a venthole in the side of the tube.
Non-conductor. A material or substance offering very high resistance to the passage of the electric current.
Non-magnetic Steel. Alloys of iron incapable of being magnetized. They are composed of iron and manganese, nickel, steel, etc.
Normal. Regular. The average value of observed quantities. Normal current is a regular current without variations.
The force of a current at which a system is intended to work.
Normal Voltage. The same as Normal Current.
North Pole. The north-seeking pole of a magnet.
The pole of a magnet which tends to point to the north, and whence lines of force are assumed to issue on their course to the other pole of the magnet.
