A much more uniform field is ob-tained by using two equal circularcoils, placed parallel to each other ata distance equal to their commonradius (264). A current of unit… … {a^ + x^fk Fig. 301. The values which this expression assumes for various values ofX are shown graphically in Fig. 301, by the ordinates of the curveA^CB2. The value ic = 0 corresponds with the centre of the circle ;the field here is greatest, and is represented by the maximumordinate q^Aj. As x…
