On tIte Determination of Coe~cients of Mutual Induction b~j ~eans of the Ballistic Galvanometer and Earth-Inductor.BZ/R.H. M. BOSANQUET ~. ¥ attention was drawn to this sub'ect~3 by the paper M recently read before the Society by Prof. FosterJ'.I observed at once that the appliances which I am in the habit of using aflbrd a very simple solution of the problem.The ballistic galvanometer has a resistance less than 2 B.A. units, and about 500 turns.I have three earth inductioncoils, all having a mean diameter of about half a metre, and the following constants.The resistances are approximate, as they vary so much with temperature.The wires are all cotton-covered copper.
