1870 London, Edinb. & Dublin Philos. Mag. 39 435 An oscillatory current..sustains itself twice as long against the damping action of resistance as a comparatively steady current of the same maximum value.

1874 London, Edinb. & Dublin Philos. Mag. 4th Ser. 47 296 The damping effect which the multiplier exerts on the swing of the needle.

1877 Ld. Rayleigh Theory of Sound I. iii. 57 The vibrations of a tuning fork properly constructed and mounted are subject to very little damping.

1879 Encycl. Brit. X. 51/1 By damping is meant the decrease of the extent of the oscillations of the galvanometer needle arising from the dissipation of energy through the resistance of the air, the action of currents induced in neighbouring metallic circuits, the viscosity of the suspension fibre, and so on.

1881 J. C. Maxwell Treat. Electr. & Magnetism (ed. 2) II. 344–5 A metallic surface, called a Damper, is sometimes placed near a magnet for the express purpose of damping or deadening its vibrations. We shall therefore speak of this kind of resistance as Damping.
