- Maxwell equations : Mathematical equations describing the interrelationship between electric and magnetic fields; dependence of the fields on electric charge- and current- densities.
- Ampere's equation : An expression for the magnetic force between two electric current-carrying wire segments.
- Ampere's law : The integral of a magnetic field over a closed path is equal to the conduction current through the surface bounded by the path.
- Biot-Savart law : Gives the magnetic field at some distance of an electric current-carrying wire.
- Gyromagnetic ratio : The constant of proportionality between the magnetic moment and angular momentum of an object.
- Magnetic constant : 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.
- Magnetic field : Vector field H caused by permanent magnets, conduction currents, and displacement currents.
- Magnetic induction : A divergence-free electromagnetic field, denoted B, determining the Lorentz force upon a moving charge, and related to the magnetic field H.
- Magnetic moment : A vector property of an object that determines the torque it experiences in a magnetic flux density.
- Magnetization : Magnetic moment per unit volume of a material, denoted M, defined in terms of the magnetic moments of its constituents by M=(1/V)Σj mj where the magnetic moment mj of the j-th constituent in the volume V is a vector property that determines the torque the object experiences in a magnetic field tending to align its moment with the field.
- Relative permittivity : A factor describing the polarizability of a material or medium as a proportionality between an electric displacement and an electric field in a dielectric.
