... So, this is all single electron terms. These define the angular momentum and spin of every individual electron. In addition next in descending order of strength, we have the inter electron coulomb repulsion. This is a two electron term so, this couples the individual electrons ((Refer Time: 06.55)) ...

... • They can travel through a vacuum. • They travel at the same incredible speed, 3.0 × 108 m/s (186,000 mi/s, in a vacuum). This is so fast that if you could set up mirrors in New York and Los Angeles, and bounce a light beam back and forth, it would make 30 round trips in just one second! (New York ...

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.
