Lern More About Magnet

Astatic :: Astatic (a.) Having little or no tendency to take a fixed or definite position or direction: thus, a suspended magnetic needle, when rendered astatic, loses its polarity, or tendency to point in a given direction..
Imponderable :: Imponderable (n.) An imponderable substance or body; specifically, in the plural, a name formerly applied to heat, light, electricity, and magnetism, regarded as subtile fluids destitute of weight but in modern science little used..
Tellurism :: Tellurism (n.) An hypothesis of animal magnetism propounded by Dr. Keiser, in Germany, in which the phenomena are ascribed to the agency of a telluric spirit or influence..
Armature :: Armature (n.) A piece of soft iron used to connect the two poles of a magnet, or electro-magnet, in order to complete the circuit, or to receive and apply the magnetic force. In the ordinary horseshoe magnet, it serves to prevent the dissipation of the magnetic force..
Ampere :: Ampere (n.) The unit of electric current; -- defined by the International Electrical Congress in 1893 and by U. S. Statute as, one tenth of the unit of current of the C. G. S. system of electro-magnetic units, or the practical equivalent of the unvarying current which, when passed through a standard solution of nitrate of silver in water, deposits silver at the rate of 0.001118 grams per second. Called also the international ampere..
Mechanico-chemical :: Mechanico-chemical (a.) Pertaining to, connected with, or dependent upon, both mechanics and chemistry; -- said especially of those sciences which treat of such phenomena as seem to depend on the laws both of mechanics and chemistry, as electricity and magnetism..
Northness :: Northness (n.) A tendency in the end of a magnetic needle to point to the north.
Paramagnetism :: Paramagnetism (n.) Magnetism, as opposed to diamagnetism..
Pole :: Pole (n.) One of the opposite or contrasted parts or directions in which a polar force is manifested; a point of maximum intensity of a force which has two such points, or which has polarity; as, the poles of a magnet; the north pole of a needle..
Diamagnetism :: Diamagnetism (n.) That form or condition of magnetic action which characterizes diamagnetics.
Induce :: Induce (v. t.) To produce, or cause, by proximity without contact or transmission, as a particular electric or magnetic condition in a body, by the approach of another body in an opposite electric or magnetic state..
Load :: Load (v. t.) To magnetize.
Sideroscope :: Sideroscope (n.) An instrument for detecting small quantities of iron in any substance by means of a very delicate combination of magnetic needles.
Diamagnetic :: Diamagnetic (a.) Pertaining to, or exhibiting the phenomena of, diamagnetism; taking, or being of a nature to take, a position at right angles to the lines of magnetic force. See Paramagnetic..
Galvanometer :: Galvanometer (n.) An instrument or apparatus for measuring the intensity of an electric current, usually by the deflection of a magnetic needle..
Biomagnetism :: Biomagnetism (n.) Animal magnetism.
Magneto-electricity :: Magneto-electricity (n.) Electricity evolved by the action of magnets.
Electro-biology :: Electro-biology (n.) That phase of mesmerism or animal magnetism, the phenomena of which are supposed to be produced by a form of electricity..
Medium :: Medium (n.) A substance through which an effect is transmitted from one thing to another; as, air is the common medium of sound. Hence: The condition upon which any event or action occurs; necessary means of motion or action; that through or by which anything is accomplished, conveyed, or carried on; specifically, in animal magnetism, spiritualism, etc., a person through whom the action of another being is said to be manifested and transmitted..
