Page 229 - Edited by JAMES AH MURRAY, LL.D., sometime President of the Philological Society ; with the assistance of many Scholars and Men of Science. Vol.
Page 4 - ... proportional to the product of their charges and inversely proportional to the square of the distance between them; and this law is valid whether the charges are equal or unequal.
Page 117 - A current of unit intensity is such that when one centimetre length of its circuit is bent into an arc of one centimetre radius, it exerts a force of one dyne on a unit magnetic pole placed at its center.
Page 51 - An electric image is an electrified point, or system of points, on one side of a surface, which would produce on the other side of that surface the tame electrical action which the actual electrification of that turface really does produce.
Page v - This book has been written with the object of supplying an Introduction to the Mathematical Treatment of Electricity and Magnetism. ... It is complete in itself, and may be read without previous knowledge of the subject. Purely experimental parts of the subject, requiring no special mathematical treatment, have been entirely omitted.
Page 70 - Magnetic Potential. The potential at any point of a magnetic field is the work which would be done by the magnetic forces of the field upon a positive unit of magnetism as it moves from that point to an infinite distance.
Page 159 - JJenz's law, which is as follows : When a conductor is moving in a magnetic field, a current is induced in the conductor in such a direction as to oppose, by its mechanical action, the motion to which the induced current is due. Another way of stating...
