Since the direction of an electric field is defined as the direction of the force on a positive charge, electric field lines point away from a positive charge and toward a negative charge.

Since light is an oscillation it is not affected by travelling through static electric or magnetic fields in a linear medium such as a vacuum.

Since large bodies such as planets generally carry no net charge, the electric field at a distance is usually zero.

Since the gyro-motion of electrons and ions is in opposite directions, an electric current flows along the boundary.

Since the theory of electric charge is dubbed " electrodynamics ", the Greek word " chroma " Χρώμα ( meaning color ) is applied to the theory of color charge, " chromodynamics ".

Since the late 1980s, numerous instrument makers, including Eric Jensen, Francois Danger, Jan Goorissen, and Jonathan Wilson, have experimented with the design and construction of electric viols.

Since the vacuum offered no medium for an electric fluid to travel, this discovery could only be explained via a particle carrying a negative charge and moving through the vacuum.

Since electromagnetism was known to be a wave generated by a changing electric or magnetic field ( a continuous, wave-like entity itself ) an atomic / particle description of electricity and charge was a non sequitur.

Since then, electric power has been used almost exclusively for powering submarines underwater, although diesel was used for powering them on the surface until the development of diesel-electric transmission by the US Navy in 1928.

Since this is an electromagnetic wave each electric field vector has a corresponding, but not illustrated, magnetic field vector that is at a right angle to the electric field vector and proportional in magnitude to it.

Since like charges repel and opposites attract, the electric field is directed away from positive charges and towards negative charges.

Since the electric field can rotate clockwise or counterclockwise as it propagates, elliptically polarized waves exhibit chirality.

Since optical frequencies are far beyond the manipulation-capacity of any feasible electronic circuit, all photon detectors are inherently energy detectors not oscillating electric field detectors.

For most bands and most small-to mid-size venues ( e. g., nightclubs and bars ), standard bass guitar speaker enclosures or keyboard amplifiers will provide sufficient sound pressure levels for onstage monitoring. Since a regular electric bass has a low " E " ( 41 Hz ) as its lowest note, most standard bass guitar cabinets are only designed with a range that goes down to about 40 Hz.

Since plasma has minimal mass, but is charged and therefore can be manipulated by an electric field, the result is a very linear output at frequencies far higher than the audible range.

Since the shields are not perfect conductors, electric fields can exist inside the shield, thus allowing radiating electromagnetic fields to go through the shield.

Since both the momentum and the current density are proportional to the drift velocity, the current density becomes proportional to the applied electric field ; this leads to Ohm's law.

Since the 1960s, the electric bass is the standard bass instrument for rock and roll, jazz fusion, heavy metal, country, reggae and pop music.

Since the Industrial Revolution, a major factor of productivity was the substitution of energy from, human and animal labor, water and wind power to electric power and internal combustion.

( D ) Since the shape of the drop conforms to the force field, it does not appreciably affect the distribution of forces in the fluid.

Since Alexander's work in the field came at the turn of the century, his ideas influenced many originators in the field of mind-body improvement.

Since then, there have been many refinements to increase the field of view, mass and position resolution, and data acquisition rate of the instrument.

Since 1998, home field advantage has been given to the team that has the better regular season record, unless that team happens to be the Wild Card team.

Since a leg theory attack means the batsman is more likely to hit the ball on the leg side, additional fielders on that side of the field can be effective in preventing runs and taking catches.

Since a maximal ideal in A is closed, is a Banach algebra that is a field, and it follows from the Gelfand-Mazur theorem that there is a bijection between the set of all maximal ideals of A and the set Δ ( A ) of all nonzero homomorphisms from A to C. The set Δ ( A ) is called the " structure space " or " character space " of A, and its members " characters.

Since the 1990s, internet communities have increasingly been the subject of research in the emerging field of cyber anthropology.

Since the NL East winners had had home field advantage in 1983, the NL West winners were entitled to it.

Since the late 19th century, differential geometry has grown into a field concerned more generally with the geometric structures on differentiable manifolds.

Since the late 1980s, the field has been revived in the wake of progress made in the related fields of psycholinguistics, neurolinguistics, evolutionary anthropology, evolutionary psychology, and cognitive science.

Since 2012, Essendon's clash guernsey has been predominantly grey, with a red sash fimbriated in black ; the grey field contains, in small print, the names of all Essendon premiership players.

Since CERT and the vendors were aware of the holes, but attempted to keep them secret even to the administrators of machines being hacked in the field, it was felt that CERT's policies were a manifestation of an impractical, " ivory tower " attitude.

Since this gas is in approximate hydrostatic equilibrium with the overall cluster gravitational field, the total mass distribution can be determined.

Since the mid-1980s, the rivalry has intensified both on and off the field and, since the inception of the Premier League in 1992, the Merseyside derby has had more players sent off than any other Premier League game.

Since the gradient coils are within the bore of the scanner, there are large forces between them and the main field coils, producing most of the noise that is heard during operation.

* Since 2006 it helped establish the Sir Arthur Clarke Award, the most prodigious award given in the United Kingdom for contribution in all field of space research and exploration.

Since the dipole magnetic field strength varies with distance as the magnetic field strength can be written as.

Since neural systems are intimately related to cognitive processes and behavior, the field is closely related to cognitive and behavioral modeling.

Since the 1970s, a large number and variety of encryption, digital signature, key agreement, and other techniques have been developed in the field of public-key cryptography.

Since this is a question of non-perturbative quantum field theory, it is difficult to find a reliable answer, but some people still pursue this option.
