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.
