By plotting and averaging he obtained the following results: Ex,cess of Deflection and straining Action of a moving Load over that due to a resting Load.
Referring to the calculations given above, this is equivalent to 1' deflection for every degree of elevation, which amount had to be given towards the higher wheel.
He regards the amount of deflection as a measure of the stability of the " ring."
Maxwell (Electricity and Magnetism, § 444), recognizing that the theory in this form gave no account of residual magnetization, made the further assumption that if the deflection of the axis of the molecule exceeded a certain angle, the axis would not return to its original position when the deflecting force was removed, but would retain a permanent set.
These arms. are then altered until on raising or depressing the battery key there is no sudden deflection either way of the galvano meter.
