Electric Currents Key to Magnetic Phenomena

Including the effects of electric currents in any description of the origin, shape, or motion of cosmic magnetized plasma is crucial for understanding many observed astronomical phenomena. The Maxwell (Heaviside) equations are based on real experimental measurements. These fundamental expressions clearly link electric current densities, magnetic flux densities, and electric fields into a unifie...

Bio-Electric Phenomena Associated with Menstruation *

The development of a vacuum tube microvoltmeter which is stable, extremely sensitive, and draws virtually no current from the system being measured has opened a new field of biological research. This instrument makes it possible for the first time to investigate quite rigorously the electrical properties of living systems. With it potential differences arising as a part of the living process ca...

Electric Phenomena in Relation to Lubrication

General. The effect of shaft currents passing through an oil film in a bearing is to accelerate polymerization and oxidation and cause thermal decomposition. The oil darkens in colour, sometimes increases in acidity, and generally deposits a chocolate-colour precipitate in the oil system. Arcing will also cause small particles of metal to flake off and contaminate the oil. If a shaft current is...

Xxiii . on the Theory of the Photo - Electric Effect

A discussion is given of the suggestion by Millikan that in the photo-electric effect the energy of the light is transferred to the free electrons of the metal as well as to the bound electrons. anrl the product of the threshold frequency and Planck's constant is interpreted to be equal to the difference between the work nec-essary to remove a ~re'e electron from the metal and the kinetic energ...
