Some properties of electric fi eld of a magnetic rotator

The article discusses an experiment in which the potential electric field of a rotating magnet is investigated. It is shown, that

intensity magnitude of an induced electric field decreases as the square of distance from the axis of rotation and the intensity of an

electric field does not depend on volume of a rotating magnet - conductor at the constant magnetic moment.

Key words: rotator, magnetized sphere, ring magnet, capacitor, electrometer, zero drift, potential, electric field, quadrupole moment.
