For almost a century after the Faraday's discovery, the "unipolar induction" had been one of the controversial issues among physical scientists. It is because the interpretation of this phenomenon was closely related to the understanding of the nature of lines of magnetic force. This paper points out the significance of the Faraday's research on unipolar induction concerning this problem: i. e. (1) His research gave the decisive conclusion that the only condition necessary for electromagnetic induction is "the motion of a conductor across lines of magnetic force". (2) His research convinced him that lines of magnetic force (today called magnetic fluxes) do exist inside a magnet forming closed circuits with those outside the magnet. Through this study, Faraday confirmed his belief that lines of magnetic force are physical existence, and that they stand still in space not revolving with the magnet.
