The fundamental or C. G. S. unit or force is the dyne, q. v. The British unit of force is the poundal (the force which will produce an acceleration of one foot per second in a mass of one pound). It is equal to about 10/322 pound. A force cannot be expressed accurately in weight [...]

Aggregations of lines of force, either electrostatic or magnetic. They generally have a truncated, conical or pyramidal shape and are not hollow. Every cross-section contains the same number of lines. The name it will seem is not very expressive.

The developing from a single force treated as a resultant, two other forces in any desired direction. The reverse of composition of forces. (See Forces, Composition of–Forces, Parallelogram of–Components–Resultant.)

When several forces act in a different direction upon a point they may be drawn or graphically represented as arrows or lines emanating from the point in the proper direction and of lengths proportional to the force they exercise. Any two can be treated as contiguous sides of a parallelogram and the parallelogram can be [...]

The usual method of composing forces or resolving a force. The sides of a parallelogram of forces represent component forces and the diagonal represents the resultant. See Component–Resultant–Forces, Composition of–Forces, Resolution of.

The force by which electric matter or electrified surfaces attract or repel each other. It is also termed electric force (not good) and electro-motive intensity. It is the mechanical force acting upon a unit quantity of electricity. Its intensity varies with the square of the distance. Its dimensions are therefore equal to (quantity * unity [...]

The mechanical force of attraction or repulsion acting on the electro-magnetic unit of quantity. Its intensity varies with the square of the distance. It may also be defined as electric force in the electro-magnetic system. Its dimensions are equal to mechanical force ((M*L)/(T^2)) divided by quantity ((M^.5)*(L^.5)) = ((M^.5)*(L^.5))/(T^2).

It is the French or metric horse power. It is equal to: 542.496    Foot lbs. per second. .9864   English Horse Power. 75.0      Kilogram-meters per second.

Force may be variously defined. (a) Any cause of change of the condition of matter with respect to motion or rest. (b) A measurable action upon a body under which the state of rest of that body, or its state of uniform motion in a straight line, suffers change. (c) It may be defined by [...]

In a dynamo with armature at the lower end of its field magnets, the plate generally of zinc, interposed between it and the iron base plate to prevent the leakage of lines of force outside of the circuit. Any diamagnetic material which is mechanically suitable may be used.
