domain/electromagnetic library
Quantity types, units and constants commonly encountered in the fields dealing with electromagnetics.
Classes
 Charge
 The property of matter that causes it to experience a force when placed in an electromagnetic field See the Wikipedia entry for Electric charge for more information.
 Conductance

The ease with which an electric current passes through a conductor (the inverse of
Resistance
). See the Wikipedia entry for Electrical resistance and conductance for more information.  MagneticFlux
 The magnetic flux density passing through a closed surface. See the Wikipedia entry for Magnetic flux for more information.
 MiscQuantity
 A MiscQuantity is a general (miscellaneous) Quantity having arbitrary dimensions (including possibly the same dimensions as a named Quantity subclass). MiscQuantity objects may be used, for example, in less common domains or as intermediate results in equations.
 Permeability
 The ability of a material to support the formation of a magnetic field within itself. See the Wikipedia entry for Permeability (electromagnetism) for more information.
 Resistance
 A measure of the difficulty passing an electric current through a conductor. See the Wikipedia entry for Electrical resistance and conductance for more information.
Constants
 bohrMagneton → const MiscQuantity
 Useful for expressing the magnetic moment of an electron caused by either its orbital or spin angular momentum.
 conductanceQuantum → const Conductance
 The quantized unit of electrical conductance. It appears when measuring the conductance of a quantum point contact, and, more generally, is a key component of Landauer formula which relates the electrical conductance of a quantum conductor to its quantum properties.
 elementaryCharge → const Charge
 The electric charge carried by a single proton.
 G0 → const Conductance
 The quantized unit of electrical conductance. It appears when measuring the conductance of a quantum point contact
 josephsonConstant → const MiscQuantity
 The inverse of the magnetic flux quantum.
 KJ → const MiscQuantity
 The common symbol for the Josephson constant.
 magneticFluxQuantum → const MagneticFlux
 The magnetic flux quantum constant is a combination of two other physical constants: the Planck constant h and the electron charge e. Its value is, therefore, the same for any superconductor.
 muB → const MiscQuantity
 The common symbol for the Bohr Magneton constant.
 muN → const MiscQuantity
 The common symbol for the Nuclear Magneton constant.
 nuclearMagneton → const MiscQuantity
 Useful for expressing magnetic dipole moments of heavy particles.
 RK → const Resistance
 The common symbol for the von Klitzing constant.
 vacuum → const Permeability
 A synonym for the magnetic constant.
 vacuumMagneticPermeability → const Permeability
 The magnetic permeability in a classical vacuum.
 vonKlitzingConstant → const Resistance
 Relates Planck's constant and the charge of the electron.
