## Subtopics

### 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 law [r]: Gives the magnetic field at some distance of an electric current-carrying wire. [e]
• 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]
• Maxwell equations [r]: Mathematical equations describing the interrelationship between electric and magnetic fields; dependence of the fields on electric charge- and current- densities. [e]

### Units

• SI [r]: Metric unit system based on the metre, kilogram, second, ampere, kelvin, mole and candela. [e]
• Gaussian units [r]: A centimeter-gram-second system of units often used in electrodynamics and special relativity. [e] (and other EM Units)
• Abampere [r]: Unit of electric current in the cgs-emu system of units; symbol abA; 1 abA = 10 A. [e]
• Statampere [r]: Electric current in the Gaussian system of units; symbol statA; 1 statA = 1 A/(10⋅c); c is the speed of light in m/s. [e]
• Abcoulomb [r]: Unit of electric charge in cgs-emu system of units; symbol abC; 1 abC = 10 C. [e]
• Statcoulomb [r]: Unit of electric charge in cgs-esu units: 1 statC = C/(10⋅c), with c the speed of light in m/s. [e]
• Maxwell (unit) [r]: Gaussian unit of magnetic flux; symbol Mx; 1 Mx = 1 abV⋅s = 10−8 Wb. [e]
