A discharge that is not oscillatory in character.

The discharge of static electricity from an excited conductor through air or rarefied gas; it is also called the quiet or silent discharge. The luminous effect in air or gas at atmospheric pressures takes the form of a little brush from a small positive electrode; the negative shows a star. The phenomena of Gassiot’s cascade, [...]

A discharge of a static charge by conduction through a conductor.

The static discharge of electricity into or through the air may be of the brush or spark form. The brush indicates the escape of electricity in continuous flow; the spark indicates discontinuity. The conditions necessary to the production of one or the other refer to the nature of the conductor, and of other conductors in [...]

In magnetism the power of maintaining itself in the plane of the magnetic meridian, possessed by the magnetic needle.

(a) The direction of an electric current is assumed to be from a positively charged electrode or terminal to a negatively charged one in the outer circuit. (b) The direction of magnetic and electro-magnetic lines of force is assumed to be from north to south pole of a magnet in the outer circuit. It is [...]

In a reflecting galvanometer the magnet used for controlling the magnetic needle by establishing a field. It is mounted on the spindle of the instrument above the coil and needle. Synonym–Controlling Magnet.

A magnet mounted in horizontal bearings at its centre of gravity. Placed in the magnetic meridian it takes the direction of the magnetic lines of force of the earth at that point. It is acted on by the vertical component of the earth’s magnetism, as it has no freedom of horizontal movement.

(a) Acid or other cleaning processes applied by dipping metals in cleaning or pickling solutions before plating in the electroplater’s bath. (b) Plating by dipping applies to electroplating without a battery by simple immersion. Copper is deposited on iron from a solution of copper sulphate in this way. Synonym–Simple Immersion.

The inclination of the magnetic needle.
