left-hand rule n. Physics a rule for finding the direction of motion of a current-carrying conductor in a magnetic field: the directions of the magnetic field, the current, and the force exerted on the conductor are indicated respectively by the first finger, second finger, and thumb of the left hand when these are held out perpendicular to each other; more fully Fleming's left-hand rule; cf. right-hand rule n. at right hand n. and adj. Compounds.

1885 J. A. Fleming in Electrician 21 Mar. 397/2 Now, let it be observed that in finding the direction of the current induced we use the right hand, but if we use the left hand instead, it provides a rule for determining the direction of motion of a conductor under the influence of a field when traversed by a current.]

1892 Electr. Rev. 15 Jan. 66/1 Left-hand rule for finding the direction of the current induced in a conductor which is moved across a magnetic field.

1934 I. M. Freeman tr. G. Joos Theoret. Physics xv. 296 The current in the segment, the magnetic field, and the ponderomotive force must form a right-handed orthogonal system in this order (Fleming's left-hand rule).

1947 Sci. News 4 117 If cosmic rays are influenced by a magnetic field, they must have a charge. Is it positive or negative? We apply the well-known Left Hand rule.

2012 Nature Chem. 4 252/2 Electrons in these solids then move in a circle, driven by the Lorenz force (recall Fleming's left-hand rule).
