The experimental results of the present investigationwhich bear upon this point must be reserved for another time, butenough of these results have been worked up to warrant the sugges-tion of the following mode of procedure, which is based on funda-mental principles. This method is only a slight modification ofthat used by Niethammer. Given a circular coil, in air, with a rectangular section whoselong side is not more than twice its short side and whose diagonalis no
