Page 89 - 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.
Page 144 - To give an example of a simple radiant field we write (, 0 -/() (163) where r is the distance of the point (x, y, z) from the origin and /(a) is a real function of a.

Page 164 - The question then naturally aris, s as to the source supplying the energy required to produce this magnetic field." "FitzGerald's view" "was that it would be found to be supplied through there being a mechanical drag on the condenser itself at the moment of charging, very similar to that which would occur were the mass...
Page 64 - ... which when multiplied by the said p reproduced / 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...
Page 156 - Jti wherein T denotes the kinetic energy and W the potential energy of the system in any configuration. The principle is supposed to be formulated in terms of any co-ordinates that are sufficient to specify the configuration in accordance with its known properties and connexions and the variation is supposed to refer to a fixed time of passage of the system from the initial to the final configuration. In the more recent investigations of Livens92 it is recognized that this simple form of Hamilton's...
