le and h is the intensity at the poleof the field due to the coil. Consider, therefore, a magnet pole of strength m placed at thecenter of the circular coil as shown in Fig. 16. This pole producesa magnetic field of which the intensity at m ac- the wire is cording to Art. 9, and the lines of force… … slim magnet Fig. 16.Circular coil of two turns with cur-rent I flowing in it and with magnetpole m at its center. is the length of the wire (Z being the number of turns of wire in the coil), and I is the strength of the current in the coil in abamperes. Now the force exerted on the coil by m is…
