Category: User-created public domain images Electric current is the flow of electric charge. ... Electromagnetic radiation can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields. ... Electromagnetism is the physics of the electromagnetic field; a field encompassing all of space which exerts a force on particles that possess the property of electric charge, and is in turn affected by the presence and motion of those particles. ... Lightning strikes during a night-time thunderstorm. ... An electrical network is an interconnection of electrical elements such as resistors, inductors, capacitors, and switches. ... To meet Wikipedias quality standards, this article or section may require cleanup. ... Electric charge is a fundamental conserved property of some subatomic particles, which determines their electromagnetic interactions. ... In physics, the Lorentz force is the force exerted on a charged particle in an electromagnetic field. ... In physics, magnetism is one of the phenomena by which materials exert an attractive or repulsive force on other materials. ... Maxwells equations (sometimes called the Maxwell equations) are the set of four equations, attributed to James Clerk Maxwell, that describe the behavior of both the electric and magnetic fields, as well as their interactions with matter. ... Current (I) flowing through a wire produces a magnetic field (B) around the wire. ... In physics, an electric field or E-field is an effect produced by an electric charge (or a time-varying magnetic field) that exerts a force on charged objects in the field. ... Electric potential is the potential energy per unit of charge associated with a static (time-invariant) electric field, also called the electrostatic potential, typically measured in volts. ... Electromagnetic induction is the production of an electrical potential difference (or voltage) across a conductor situated in a changing magnetic flux. ... The factual accuracy of this article is disputed. ... In physics and mathematical analysis, Gausss law gives the relation between the electric flux flowing out a closed surface and the electric charge enclosed in the surface. ... In physics, Coulombs law is an inverse-square law indicating the magnitude and direction of electrostatic force that one stationary, electrically charged object of small dimensions (ideally, a point source) exerts on another. ... Various solenoid actuators from Trombetta Motion Technologies A solenoid is a loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electrical current is passed through it. ... An electric current produces a magnetic field. ... Electrostatics is the branch of physics that deals with the forces exerted by a static (i. ... Classical electrodynamics (or classical electromagnetism) is a theory of electromagnetism that was developed over the course of the 19th century, most prominently by James Clerk Maxwell. ... In physics, the magnetic moment or magnetic dipole moment is a measure of the strength of a magnetic source. ... Displacement current is a quantity related to a changing electric field. ... Faradays law of induction (more generally, the law of electromagnetic induction) states that a magnetic field changing in time creates a proportional electromotive force. ... This article needs to be cleaned up to conform to a higher standard of quality. ...
