A relay, comprising:

• a contact container having a contact chamber and a pair of first through holes in communication with the contact chamber;
• a pair of static contact leading-out terminals passing through the pair of first through holes, respectively;
• a moving part movable relative to the contact container;
• a first magnetizer arranged within the contact chamber and connected with the moving part;
• a movable member movably arranged within the contact chamber and comprising a movable contact piece, the movable contact piece configured to come into contacting with or separating from the pair of static contact leading-out terminals;
• the first magnetizer being arranged at one side of the movable contact piece facing the static contact leading-out terminals;
• and
• a fixing magnetizer, fixedly arranged within the contact chamber, the fixing magnetizer being arranged at one side of the first magnetizer facing away from the movable contact piece,
• wherein the first magnetizer is movable relative to the movable member through the moving part and is configured to adjust a distance between the first magnetizer and the movable member according to a value of a current flowing through the movable contact piece.
