The　influence　of　magnetized　water　on　the　electrical　properties　of　ZnO　varistor　ceramics　was　investigated　by　electrical　property　measurement　and　frequency　spectrum　technology.　It　was　found　that,　compared　with　results　of　deionized　water,　higher　varistor　voltage　E-lmA　and　lower　non-linear　coefficient　a　can　be　achieved　by　using　0.2T　magnetized　water,　while　E-lmA　and　alpha　of　0.3T　magnetized　water　are　close　to　deionized　water　results.　Furthermore,　the　frequency　spectrum　of　magnetized　water　reveal　that　the　change　of　ZnO　varistors　closely　related　to　the　dielectric　performance　of　magnetized　water　of　various　magnetized
