The paper deals with the issue of induced EMF localization in a Faraday’s unipolar generator which is a revolving magnetic disk with its center and periphery connected by a conductor. Attention has also been given to the linear DC generator consisting of a long magnet and a conductor. Functioning as a closed loop, this conductor moves within the magnetic field of the magnet, the ends sliding on its surfaces. It is shown that in a linear unipolar generator the EMF is induced in a conductor irrespective of a reference frame chosen. Reasons are given in favour of the fact that when a magnetic disk is revolving, the EMF is induced in a stationary conductor of a unipolar generator.
