Self-inductance is the voltage produced by the changing of the electric current through a circuit that contains inductance, which opposes the change in ... more

In plasma physics, an Alfvén wave, named after Hannes Alfvén, is a type of magnetohydrodynamic wave in which ions oscillate in response to a restoring ... more

The magnetic Reynolds number is the magnetic analogue of the Reynolds number, a fundamental dimensionless group that occurs in magnetohydrodynamics. It ... more

The magnetic diffusivity is a parameter in plasma physics which appears in the magnetic Reynolds number.

A magnetic dipole is a closed circulation of electric current. A simple example of this is a single loop of wire with some constant current through ... more

Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. The induced ... more

The mutual inductance factor depends on the number of turns each coil and the permeance of the space occupied by the flux

The Gilbert model assumes that the magnetic forces between magnets are due to magnetic charges near the poles. This model produces good approximations that ... more

The magnetic energy stored by a coil carrying a current is given by one half of the inductance of the coil times the square of the current

Hydraulic conductivity is a property of vascular plants, soils and rocks, that describes the ease with which a fluid (usually water) can move through pore ... more
