PURPOSE: A magnet assembly for convergence where a magnet with an asymmetric polarity is formed is provided to increase a fine tuning which improves a productivity by minimizing fabrication costs and thus to improve an economical efficiency of the whole CRT(Cathode Ray Tube) convergence. CONSTITUTION: According to the convergence, three magnet rings(10,20,30) of P polarity, 4 polarity and 6 polarity forming a magnetic pole with two sheets and one pair and a spacer(40) intervened between each magnet ring to block an interference of the magnet rings are inserted in sequence into a nonmagnetic holder(50). And a spacer magnetized with additional asymmetric even polarity above two polarity which can control a CCV(Centerside Convergence Value) and an OCV(Outside Convergence Value) at the same time by inducing a displacement of side beams(R beam, B beam) among R, G, B beam when each magnet ring is in a minimum magnetic state is intervened in a fixed place of the magnet assembly.
