Infinity ring formed by the magnetic nanoparticles

Pictured is an infinity ring formed by the magnetic nanoparticles in response to the magnetic field. The center of the infinity ring represents the ballistic transport where nanoparticles are accumulated, whereas the lighter shade of the ring shows the diffusive transport where nanoparticles are free and diffusing away. This very fundamental process of magnetophoresis is central to various biomedical applications and it also has been protecting the Earth by deflecting the charged particles in the magnetosphere. Ayansiji et al. have developed a predictive model to understand and control magnetophoresis.
