1873 J. C. Maxwell Treat. Electr. & Magnetism II. 7 When a dipolar quantity is turned end for end it remains the same as before. Tensions and pressures in solid bodies, Extensions, Compressions and Distortions, and most of the optical, electrical, and magnetic properties of crystallized bodies are dipolar quantities.

Thomson Math. & Physical Papers I. xlviii. §168. 283 The rotatory property with reference to light discovered by Faraday as induced by magnetization in transparent solids which I shall call dipolar, to distinguish it from such a rotatory property with reference to light as that which is naturally possessed by many transparent liquids and solids, and which may be called an isotropic rotatory property.

1884 P. G. Tait Light §298 Along the axis of a crystal of quartz there is dipolar symmetry; along the lines of force in a transparent diamagnetic there is dipolar asymmetry.
