title: Magnetic Damping of Rotation of Satellite 1958beta2.
abstract: From over 200 observations of the decreasing spin rate of Vanguard I made during the year since its launching, eddy-current induction theory yields 0.115 +/- 0.001 gauss as the mean magnetic field normal to the spin axis of the satellite. This measured value agrees with that deduced from Bauer's model of the earth's dipole field.
