solenoidal, a.|sɒl-, səʊləˈnɔɪdəl|
[f. prec. + -al1.]
Of, pertaining or relating to, a solenoid; of the nature or having the properties of a solenoid. spec. of a vector field: having no divergence anywhere, and hence expressible as the curl of another vector field.
1873Maxwell Electr. & Magn. I. 21 The distribution of the vector quantity is said to be Solenoidal. 1873J. C. Maxwell Electr. & Magnetism I. 23 The whole space can be divided into tubes of this kind provided dX/dx + dY/dy + dZ/dz = o, a distribution of a vector quantity consistent with this equation is called a Solenoidal Distribution. 1883Encycl. Brit. XV. 230/2 Solenoidal Magnets..[are] such that the vector I satisfies the solenoidal condition. 1897Curry Theory Electr. & Magnetism 256 This solenoidal arrangement of the molecular currents. 1909J. G. Coffin Vector Anal. vi. 154 (heading) Separation of a vector point-function W, which has a vector-potential, into solenoidal or rotational and lamellar or irrotational components. 1933H. Phillips Vector Anal. viii. 195 If two vectors satisfy these conditions their difference, being irrotational, solenoidal, piecewise continuous, and zero at infinity, is zero. 1972A. G. Howson Handbk. Terms Algebra & Anal. xxxv. 175 A vector field satisfying div f = 0, i.e. div f(x) = 0 for all x {elem}S, is said to be solenoidal.
Hence soleˈnoidally adv.
