A measure of the quantity of magnetism, being the total number of magnetic lines of force passing through a specified area in a magnetic field.
The component of a magnetic field perpendicular to an area multiplied by the size of that area; a measure of the number of magnetic field lines passing through the area: it is measured in maxwells or webers.
The lines of force associated with a magnetic field. The strength of magnetic flux is equivalent to its magnetic flux density per unit area. The SI unit of magnetic flux is the weber.
In a uniform magnetic field of unit intensity formed in empty space the induction or magnetic flux across an area of I square centimetre normal to the direction of the field is arbitrarily taken as the unit of induction.
The magnetic flux per square centimetre at any point (B, B, or 0) is briefly called the induction, or, especially by electrical engineers, the flux-density.
When the armature is rotated, these two coils endeavour to place themselves in certain directions in the field so as to be perforated by the greatest magnetic flux.
