WebLet (r) be an arbitrary scalar function. A magnetic field which satisfies B = B is called force-free because the Lorentz force density j(r) B(r) vanishes everywhere. There is some evidence that fields of this sort exist in the Suns magnetic environment.(a) Under what conditions is the sum of two force-free fields itself force-free?(b) Let (r) = WebTranscript. Scalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction.
