Consequent poles

One should never assume, without prior test, that a bar magnet always has opposite poles at its ends. If a steel bar is magnetized by divided touch using two S poles we obtain a N pole at both ends of the bar and a double S pole ill the center. In this condition the bar is said to possess consequent poles (Fig. 30.7).
