Guiding Center
In many cases of practical interest, the motion in a magnetic field of an electrically charged particle (such as an electron or ion in a plasma) can be treated as the superposition of a relatively fast circular motion around a point called the guiding center and a relatively slow drift of this point. The drift speeds may differ for various species depending on their charge states, masses, or temperatures, possibly resulting in electric currents or chemical separation.

Famous quotes containing the words guiding and/or center:
“We are born to action; and whatever is capable of suggesting and guiding action has power over us from the first.”
—Charles Horton Cooley (1864–1929)
“Whenever there’s a big war coming on, you should rope off a big field. And on the big day, you should take all the kings and their cabinets and their generals, put ‘em in the center dressed in their underpants and let them fight it out with clubs. The best country wins.”
—Maxwell Anderson (1888–1959)
