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:
“Parents must not only have certain ways of guiding by prohibition and permission; they must also be able to represent to the child a deep, an almost somatic conviction that there is a meaning to what they are doing. Ultimately, children become neurotic not from frustrations, but from the lack or loss of societal meaning in these frustrations.”
—Erik H. Erikson (20th century)
“It is written in the Book of Usable Minutes
That all things have their center in their dying....”
—John Ashbery (b. 1927)
