ilar reasoning it may be shown that A is urged towards Bivith a force 2i2i1/r per centimetre of its length. Further, we see that currents in the same direction attract each other,ind currents in opposite directions repel each other. When the circuits are not of such a simple form, it may not be,asy… … Kelvin current balance.—The current to be measured passes throughix coils CLMABD in series (Fig. 909). A, B, C and D are fixed, while. and M are attached to an armvhich can rotate about an axis<H. A scale is also attached tohe arm and carries a weight Wvhich can be caused to slidelong this…
