† magnusn.¹

Origin: A variant or alteration of another lexical item; perhaps modelled on a Latin lexical item, or perhaps modelled on a proper name. Etymon: manganese n.

Etymology: Variant of manganese n. (compare magnase n.), with elision, and spelling perhaps influenced by classical Latin magnus great or its derivative. the personal name Magnus (dedication of a major church near London Bridge; c1114 as a surname in Staffordshire).Compare:1880 C. H. Poole Attempt Gloss. Stafford 15/2 Magmes, a name given to Manganese. N.E.D. (1904) indicates the stress as ˈmagnus.

Obsolete.

Manganese oxide.

Magnusn.²

Brit.

/ˈmaɡnəs/, U.S.

/ˈmæɡnəs/

Origin: From a proper name. Etymon: proper name Magnus.

Etymology: < the name of Heinrich G. Magnus (1802–70), German physicist and chemist, who described the effect ( Physikalische Abhandlungen der Königlichen Akad. der Wissensch. zu Berlin (1853) 1).

1. Magnus effect n. the effect of rapid spinning on a cylinder or sphere moving through a fluid in a direction at right angles to the axis of spin, which results in a sideways force at right angles to both the direction of motion and the axis of spin and towards the side where the peripheral motion of the body is in the opposite direction to its overall motion.Prior to Magnus's publication the phenomenon had been referred to by Newton ( Philos. Trans. Royal Soc. (1672) 6 3078); it is also mentioned in B. Robins New Princ. Gunnery (1742) ii. 93.

1921 tr. Cranz & Becker's Handbk. Ballistics I. 314 A quantitative theory of the deviation of a sphere under the influence of the adhering air (Magnus effect) was attempted..by Tait.

1925 Flight 8 Jan. 14/1 It does not appear to be until quite recently that the idea of applying the Magnus effect has occurred to anyone.

1943 R. C. Binder Fluid Mech. xi. 143 The Flettner rotor, which employs the Magnus effect, has been applied to the propulsion of marine vessels. Vertical cylinders are extended some distance above the deck. Each cylinder is rotated about its axis by a small motor, and an air force is produced for moving the craft.

1973 Sci. Amer. Apr. 121/2 The drag of the turbulent wake and the sidewise forces of the Magnus effect (the name given the transverse forces produced by the flow pattern around a spinning ball) are carefully considered. They are at the heart of baseball, tennis, golf and high-quality soccer.

1992 Physical Rev. A. 45 8204/1 Looking at a rotating ping-pong ball falling through the air, we can see that it is deflected from the vertical towards the direction of rotation due to the Magnus effect.

2. Magnus force n. a force on a rotating body arising from the Magnus effect.

1968 C. G. Kuper Introd. Theory Superconductivity iii. 38 The term in grad(½J²/ _S) leads to the Magnus force on Abrikosov's (1957) quantized flux lines.

1990 New Scientist 28 July 40/1 For Frisbees, the magnitude of the Magnus force depends on the disc's width and the speed of its rotation relative to that of the flow.

1997 Sci. Amer. Sept. 84 With a typical spin of 1,600 revolutions per minute, the Magnus force is only about 20 percent of gravity, so the ball drops only about 2.4 feet.
