Abstract: In this paper some methods for measuring magnetic fields are described coneisely and a comparison between these methods is made. The general theory and experiment-al method for measuring the TV deflecting magnetic field are given in detail. A practical measuring set up is presented. The curves of the magnetic field parameters H0(z), H2(z) and H4(z) are shown. -
