(a) Draw the elementary magnets inside a bar magnet and a horseshoe magnet, using the half-filled-circle format shown in Figures 27.8 and 27.9.

(b) How many poles does the magnetized ring in Figure \(\mathbf{2 7 . 1 0}\) have?

(c) If someone gave you such a ring, how could you verify that it is indeed magnetized as illustrated?

Figure 27.8 The concept of elementary magnets explains why cutting a magnet in two reveals new N and S poles. (a) 0000 1 N In magnetized material, elementary magnets (0) are aligned... 00000000 (b) 00000000 (00000000 00000000 ... so splitting magnet exposes two new poles.
