Abstract

Convection inside a polymer solution sessile droplet under a strong magnetic field is numerically studied. The droplet presumed is a diamagnetism solution, which has different magnetic susceptibility between solute and solvent. The magnetic field is presumed by a single electric coil. The coil placed in a lower position induces the upward force near the surface, which enhances the Marangoni convection. If the coil is located above the droplet, the flow is suppressed by the downward force. These effects are found to be remarkable for a large droplet.

This study is partially supported by MEXT, Grant-in-aid for Young Scientists (B) No. 19760528. The authors are grateful to Dr. Toshio Tagawa for the fruitful discussions of the measurement of magnetic susceptibility.
