(The number of) lines of magnetic induction ( magnetic flux) or electric displacement ( electric flux); the quantity of flux through any surface is equal to the integral of the normal component of the induction or displacement over the surface.

Electr. & Magnetism I. 11 Electric and magnetic induction, and electric currents, belong to the second class, being defined with reference to areas. When we wish to indicate this fact, we shall refer to them as Fluxes. 1898 J. A. Fleming Magnets & Electr. Currents iii. 65 If..a disc of iron is placed in a uniform field of magnetic force, the flux concentrates itself in the iron. 1911 W. F. Magie Princ. Physics xix. 452 The theorems concerning electric flux are similar to those concerning magnetic flux. 1933 E. Mallett Vectors for Electr. Engineers iv. 52 The e.m.f. produced by the alternating flux in the primary coil. 1957 B. I. Bleany & B. Bleaney Electr. & Magn. vi. 147 If the two coils are closely wound..then the ratio of the two fluxes N1 and N2 will just be equal to the ratio of the number of turns n1, n2 on the two coils. 1969 L. Young Syst. Units Electr. & Magn. iv. 42 The flux ‘lines’ spread out over space to produce a certain electric flux density or electric displacement. < as lemmas |
