t;» m/*& B~UjIdz-¥B is therefore independent of the medium, thus fulfilling the condi-tion required. Thus, the definition of magnetic induction is that it isif times the strength of magnetic field at any point where H is defined ason p. 781 and ju as defined on p. 811. Magnetic lines of… … Fig. 749.—Lines of induction. lines, however, are continuous with others within the magnet, sothat each line in its entire path forms a closed circuit (Fig. 749);but within the magnet they are not lines of force, that is to say,they do not by their number per unit area, represent the strengthof…
