2006 USA Today (Nexis) 13 Oct. 1 a This year's self-reversal exemplifies the central political mystery of Arnold Schwarzenegger: continual change that has kept voters and politicians guessing whether [he]..is at heart a Republican, a Democrat or a combination of the two.

1883 Electrician 20 Jan. 222/2 The only defect of the [Voss induction] machine is a tendency to self-reversal, which is apt to occur at a stoppage.

1910 U.S. Patent 946,558 3/1 Means serving to prevent the body from traveling beyond the limits of self-reversal or return movement by gravity.

1905 E. C. C. Baly Spectroscopy xii. 384 The lines generally were sharper than in the case of the arc in air,..and there were fewer self-reversals.

1934 H. E. White Introd. Atomic Spectra xiv. 250 The centers of the potassium-doublet, the calcium-singlet, and the copper-doublet lines show self-reversal due to absorption.

1977 A. Corney Atomic & Laser Spectroscopy x. 313 Systematic errors are difficult to avoid in these experiments since the profile..is usually considerably distorted by self absorption or even self reversal.

1971 Nature 5 Feb. 378/1 At this point [sc. the early 1950s] an alternative to field reversal began to receive serious consideration. This was self-reversal, the possibility that some rocks possessed an intrinsic property whereby they could acquire a magnetization antiparallel to the ambient field, or whereby an originally parallel magnetization could reverse spontaneously.
