Magnetic fluids are used in many different areas, including medicine, electronics, mechanical engineering, ecology, etc. Such a wide range of applications is explained by a number of its useful properties. Researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) in collaboration with colleagues from Jiangsu Normal University (JSNU) discovered new effects in magnetic fluids, which will increase its effectiveness for medical purposes in future. The results were published in Springer Proceedings in Physics.
