Search for monopoles using superconducting quantum interference device (SQUID) Y. H. Yuan∗ (Dated: December 23, 2005) The discovery of magnetic monopoles would be of fundamental significance in the research of 6 modern physics. In this paper, we present a short review of the history of magnetic monopole 0 research. The theoretical work and experimental technique in the search for magnetic monopoles 0 using SQUID (superconducting quantum interference device) are investigated. We also discuss 2 the properties of magnetic monopole and propose neutrinos have magnetic charges and a possible experimental test based upon the Faraday induction method. b e F I. INTRODUCTION have been carried out[6, 7, 8, 9, 10, 11, 12, 13]. Thanks 0 to the proposal due to Dirac. Although we have not 2 The existence of the magnetic monopole was one of observed magnetic monopoles, the elusive monopole has ] the open questions of modern physics. In 1931, P.
