I Calculating the curvature drift in a plasma

  1. May 24, 2018 #1
    How do i get this equation,

    This equation is a vector whose direction is towards the centre of the circle which most closely approximates the magnetic field-line at a given point, and whose magnitude is the inverse of the radius of this circle.

    However I have no idea how to obtain the above and the source basically state it as by definition. Where is this equation obtained from?
