▪ I. magnetoid, n. Astron.|ˈmægnɪtɔɪd|
[ad. Russ. magnitoid (coined by L.M. Ozernoĭ 1966, in Astron. Zhurnal XLIII. 301): see magnet n., -oid.]
A hypothetical supermassive rotating body of magnetized plasma, postulated to account for the huge energy output of quasars. Cf. spinar n.
1966tr. L. M. Ozernoĭ in Astron. Zhurnal XLIII. 301 A quasistationary configuration—magnetoid is considered for the construction of an idealized scheme of multivarious phenomena occurring in galactic nuclei and especially in the central parts of quasistellar radio sources. 1970Nature 19 Dec. 1175/1 The most plausible hypothesis to explain the activity of QSOs and galactic nuclei seems to be the so-called ‘magnetoid’ hypothesis. 1977Astron. & Astrophysics LVI. 166/2 We will consider the simplest realization of a magnetoid i.e. in the form of a supermassive oblique rotator..having solid-body rotation and quasi-dipole magnetic field. 1984Q. Jrnl. R. Astron. Soc. XXV. 28 We use the term ‘spinar’ even though the term ‘magnetoid’ would be equally well applicable.
▪ II. magnetoid, a.|mægˈniːtɔɪd|
