The Link between Electric Current and Magnetic Field The Double
... We now need to explain how the electric current in the wire starts the process off in the first place. We know that the process only begins when the current in the wire is accelerating. It takes translational acceleration of electric current to increase a magnetic field. If this translational accele ...

... is found in Page (1998). Using a typical “standard” cooling curve for a neutron star, one finds that the magnetic field of an isolated neutron star would decay by some amount in the first ∼ 105 yr, when the star is still relatively hot, and thereafter remain constant (cf. Urpin & Van Riper 1993). Th ...

Magnetohydrodynamics
Magnetohydrodynamics (MHD) (magneto fluid dynamics or hydromagnetics) is the study of the magnetic properties of electrically conducting fluids. Examples of such magneto-fluids include plasmas, liquid metals, and salt water or electrolytes. The word magnetohydrodynamics (MHD) is derived from magneto- meaning magnetic field, hydro- meaning water, and -dynamics meaning movement. The field of MHD was initiated by Hannes Alfvén, for which he received the Nobel Prize in Physics in 1970.The fundamental concept behind MHD is that magnetic fields can induce currents in a moving conductive fluid, which in turn polarizes the fluid and reciprocally changes the magnetic field itself. The set of equations that describe MHD are a combination of the Navier-Stokes equations of fluid dynamics and Maxwell's equations of electromagnetism. These differential equations must be solved simultaneously, either analytically or numerically.
