eld. — The advantage of the above method of treating the motionof a small coil in a magnetic field is that the rule just derivedis applicable to all circuits, whether movable in parts or asa whole. The generalization is due to Maxwell, who statedit essentially as follows: Every conductor conveying… … Fig. 252. This principle is illustrated in the apparatus shown inFig. 252. G-P is a movable conductor supported on a pivot.G-, resting in a mercury cup. P. and dipping into a trough ofmercury at P. A wire, ZA. joins the battery B in circuitwith the cup and the trough. The current starting fromthe…
