The invention provides a method for preventing a joint of an iron handrail and concrete of a bridge from being rusted and broken by using magnetic slurry, which comprises the following steps of: repairing the rusted iron handrail by using the magnetic slurry, and carrying out magnetizing pretreatment on an iron handrail newly leaving a factory so as to prevent the iron handrail from being rusted, the magnetic slurry is covered by a special non-magnetic material floral tube after being wrapped on the iron handrail, the special non-magnetic material floral tube is sealed by water swelling rubber, and the magnetic slurry achieves the effect of covering the iron handrail by magnetizing the iron handrail or applying an electromagnet. According to the method, overwater or underwater easily-rusted structures including but not limited to bridge iron handrails and the like can be repaired and prevented from being rusted, and the method has wide engineering practical significance and application prospects. 本发明提供了一种磁性浆液
