Glazebrook, Richard, Sir, 1854-1935 · Cambridge : The University press · leaf 343
e product of the strengthof the field and the current, and perpendicular to both the wireand the lines of magnetic force, and acts in the direction inwhich the strength of the field decreases, will enable us toaccount for the attractions and repulsions observed, and it isa consequence of theory… … Fig. 202. The lines of force due to the current i are the dottedcircles. 334 ELECTRICITY [CH. XX Let JiO W be the east and west line through 0. At a point P between 0 and E the force due to the.current is opposite to that due to the field, to the west of 0the reverse is the case, thus the field is…
