ncomparison with the dimensions ofthe needle, if we are to assume thatthe field in which the needle hangs isuniform. A much more uniform field is ob-tained by using two equal circularcoils, placed parallel to each othei ata distance equal to their commonradius (264). A current of unit strength… … Fig. 301. The values which this expression assumes for various values ofX are shown graphically in Fig. 301, by the ordinates of the curveA.CBj. The value x = 0 coixesponds with the centre of the circle ;the field here is greatest, and is represented by the maximumordinate Q^Aj. As -■ increases,…
