This paper introduced the magnetization induction technology, principle, and its application in water ecological restoration, believing that the magnetization induction effect can play an important role in aquatic animal population optimization, aquatic plant restoration, and sediment restoration, with the advantages of strengthening the existing water ecological restoration technology and decreasing the restoration cost. In the future, further research should be carried out on the multiple magnetization parameters, the differences mechanism of different biological magnetic effect, multiple aquatic biological composite magnetic effects and the application of large water magnetization methods.
