of the iron is reversed, the north pole now being at the end where the south pole was before, and vice versa.
169. Lines of Force as a Measure of the Magnetic Field. — It has been explained (93) that a conductor conveying an electric current is surrounded by a field of ma...gnetic force, and that in such a field, the lines of force are concentric with the conductor.
These lines of force may be regarded as units, in terms of which magnetism may be expressed and measured.
The direction and polarity of the magnetic force is indicated by the direction and polarity of the lines, the total number of its lines is a measure of the total quantity of magnetism, while the number of them contained in a given unit of area, measured in a direction perpendicular to their direction, is a measure of the intensity of magnetism at that point.
