Abstract :In this study, the results of experimental studies of two practical applications of magnetic fluid are presented. In the first example, the core of the air core small size transformer, whose body is made of non-magnetic material, was filled with magnetic fluid and the output voltage characteristics of different frequencies were investigated. In the second model, the use of magnetic fluids in order to weaken the negative effects of the small cracks and crevices formed on the cores side arms of the industrial transformers to the output characteristics of the transformers were examined. For this purpose, the channels of different types of transformers of the 220V / 12V low-voltage transformers with a 5W power rating of industrial PCB type were filled with magnetic liquid and the characteristics of the transformer were examined. In order to increase the magnetization properties of magnetic fluids, pure iron powder  insert ignore into journalissuearticles values(Fe 3 O 4 );   was added to these fluids and experimental investigations were performed. The positive results were evaluated in tables and graphs.
