Seite 87 - No mere rotation of a bar-magnet on its axis produces any inductive effects on circuits exterior to it. The system of power about the magnet must not be considered as revolving with the magnet any more than the rays of light which emanate from the sun are supposed to revolve with the sun. The magnet may even, in certain cases, be considered as revolving amongst its own forces, and producing a full electric effect sensible at the galvanometer.

Seite 62 - ... would be obviously nothing more than a manipulation of symbols. Our desire is to emphasize the fact that, until some further assumption is made, there is no connection whatever between the velocity of the boundary of our charge and the v which occurs in equation (97). Co-existent with any set of motions which we like to assign to the boundaries of the charges, /, ie, pv can have any values whatever, as far as our definitions are concerned, and this is what might be expected in view of the fact...
