Figure 2(a) The magnetic field of a single bar magnet is revealed by a number of compasses. (b) The field in one plane is represented by a series of directed lines that by convention
emerge from the N-pole and curve toward the S-pole. (c) Iron filings show the field clearly but do not reveal the pole orientation.
