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… … Fig. 203. 203] ELECTROMAGNETISM 335 current to the west of 0, weakened to the east. According tothe law the conductor is driven from west to east by theelectromagnetic force with a force per unit length equal to Hi.If the current be upwards the magnetic force is from east towest.
