Parent topics
- Electron [r]: Elementary particle that carries a negative elementary charge −e and has mass 9.109 382 91 × 10−31 kg. [e]
- Electricity [r]: The flow or presence of electric charge; the flow of electricity is an important carrier of energy. [e]
- Magnetism [r]: Property of attracting iron. [e]
- Electric field [r]: force acting on an electric charge—a vector field. [e]
- Magnetic field [r]: Vector field H caused by permanent magnets, conduction currents, and displacement currents. [e]
- Electromagnetic induction [r]: Electromotive force induced by a varying magnetic field; described by Faraday's law of induction. [e]
- Electromagnetic radiation [r]: a collection of electromagnetic waves, usually of different wavelengths. [e]
- Electromagnetic wave [r]: A change, periodic in space and time, of an electric field E(r,t) and a magnetic field B(r,t); a stream of electromagnetic waves, referred to as electromagnetic radiation, can be seen as a stream of massless elementary particles, named photons. [e]
- Elementary charge [r]: Charge of electron (negative) and proton (positive); before discovery of the quark thought to be the smallest possible electric charge, written , value 1.602 176 53(14) × 10−19 C [e]
- Magnetic constant [r]: A physical constant in the International System of Units (SI) relating mechanical force and electric current in classical vacuum with a defined value μ0 = 4π × 10−7 N/A2. [e]
- Magnetic flux [r]: Is the total magnetic induction B integrated over a surface S. [e]
- Magnetic induction [r]: A divergence-free electromagnetic field, denoted B, determining the Lorentz force upon a moving charge, and related to the magnetic field H. [e]
- Displacement current [r]: Time derivative of the electric displacement D; Maxwell's correction to Ampère's law. [e]
- Lorentz force [r]: Force on an electrically charged particle that moves through a magnetic and an electric field. [e]
Laws and equations
- Ampere's equation [r]: An expression for the magnetic force between two electric current-carrying wire segments. [e]
- Ampere's law [r]: The integral of a magnetic field over a closed path is equal to the conduction current through the surface bounded by the path. [e]
- Ampere's rule [r]: Is a right-hand rule for the direction of deviation of a compass needle caused by the presence of a straight, electric-current carrying, wire. [e]
- Biot-Savart's law [r]: Add brief definition or description
- Coulomb's law [r]: An inverse-square distance law, like Newton's gravitational law, describing the forces acting between electric point charges; also valid for the force between magnetic poles. [e]
- Coulomb's law (magnetic) [r]: An inverse-square law for the force between two magnetic monopoles. [e]
- Faraday's law (electromagnetism) [r]: States that a change in magnetic flux generates an electromotive force (EMF). [e]
- Gauss' law (electrostatics) [r]: Relates the surface integral of the electric displacement through a closed surface to the electric charge enveloped by the closed surface. [e]
- Gauss' law (magnetism) [r]: States that the total magnetic flux through a closed surface is zero; this means that magnetic monopoles do not exist. [e]
- Lenz' law [r]: States that a change in magnetic flux gives an induced current that opposes this change. [e]
