Electric current produces a magnetic field.

Electric field lines of two opposing charges separated by a finite distance.

The efforts of the two did much to further electrical engineering — Tesla's work on induction motors and polyphase systems influenced the field for years to come, while Edison's work on telegraphy and his development of the stock ticker proved lucrative for his company, which ultimately became General Electric.

Electric field of a positive and a negative point charge.

* Electric field integration

* Electric field screening

Electric field lines emanating from a point positive electric charge suspended over a negatively-charged infinite sheet

Electric fields contain electrical energy with energy density proportional to the square of the field amplitude.

Electric field lines for this mode have a longitudinal component and require line lengths of a half-wavelength or longer.

Electric field measurements in thunderclouds are typically not large enough to directly initiate a discharge.

Electric current flowing in the coils of the tape head creates a fluctuating magnetic field.

Electric sparks require a field strength above about 4 KV / cm in air, as notably occurs in lightning strikes.

Field Emission Electric Propulsion ( FEEP ) is an electrostatic propulsion concept based on field ionization of a liquid metal and subsequent acceleration of the ions by a strong electric field.

* Electric sensors at the ends of opposing booms are used to measure potential differences between separated points, to derive electric field associated with convection.

Interest in robotics increased in the late 1970s and many US companies entered the field, including large firms like General Electric, and General Motors ( which formed joint venture FANUC Robotics with FANUC LTD of Japan ).

Telephones made by Western Electric prior to the breakup continued to be manufactured and continued to be marked " Western Electric ", with the Bell logo absent, or " hidden " by metal filler inside of all telephone housings and most components, including new electronic integrated circuits with the " WE " initials.

General Electric performed preliminary testing on some of the components of the MOOSE system, including flying samples of heat shield material on a Mercury mission, inflating a foam-filled bag with a human subject embedded inside, and test-dropping dummies in MOOSE foam shields short distances.

The power station is also promoted as a Welsh tourist attraction, with visitors able to take a minibus trip to see the workings inside the so-called " Electric Mountain ".

Electric powered tools are useful for locations where access to a compressor is limited or impractical, such as inside a building, in a crowded constructin site, or in a remote location.

Electric Garage Door openers did not become popular until Era Meter Company of Chicago offered one after World War II where the overhead garage door could be opened via a key pad located on a post at the end of the driveway or a switch inside the garage.

After several failed attempts at collecting hearts, she tries to use one of Eudial's abandoned inventions ( Witches Electric Warp ). The machine would transport a person inside of a television, which would increase that person's power exponentially.

Electric guitars can have solid, semi-hollow, or hollow bodies, and produce little sound without amplification.

Released by the Gibson Guitar Corporation as part of its ES ( Electric Spanish ) series in 1958, it is neither hollow nor solid ; instead, a solid wood block runs through the center of its body.

Electric guitars do not usually have bridge pins as, in guitars, they are used to transfer the sound from the strings into the hollow body of the instrument as well as holding the strings in place.

Electric guitar saddles are typically metal, though some synthetic saddles are available.

RCA was a major producer of vacuum tubes ( branded Radiotron ) in the US, creating a series of innovative products ranging from octal base metal tubes co-developed with General Electric before WWII to the transistor-sized Nuvistor used in the tuners of the New Vista series of TV sets.

Electric models are powered by small but powerful electric motors and rechargeable nickel-cadmium, nickel metal hydride, or lithium polymer cells.

Electric folk also gave rise to the subgenre of Medieval folk rock and the fusion genres of folk punk and folk metal.

The genre is strongly influenced by the early work of Black Sabbath, who formed a prototype for doom metal with songs such as " Black Sabbath ", " Electric Funeral " and " Into the Void ".

Electric current will flow from the anodic areas into the electrolyte as the metal corrodes.

Derakh had previously gained some fame in the 1980s metal band Rough Cutt, and Hewitt was a former member of Electric Love Hogs.

Electric Six is a six-piece Detroit-based band that plays what has been described as a brand of rock music infused with elements of " Garage, disco, punk rock, New wave, and metal.

Doom metal band Electric Wizard included a song called Dunwich on its album Witchcult Today

Electric Wizard are a doom metal band from Dorset, England that formed in 1993.

Electric Wizard have a distinct yet traditional doom metal sound that incorporates stoner and sludge traits, with lyrics typically involving the occult, witchcraft, H. P.

It was Electric Wizard's most experimental record, adopting an aggressive sound similar to sludge metal.
