One of the advantages of crystal growth under microgravity conditions is the damping of solute convection that deteriorates crystal quality. However, there have been few methods to damp solute convection on the earth. When crystals grow floating at the air-solution interface, solute convection is damped considerably. It is proved to be possible to float some protein crystals by applying a magnetic field gradient even when all of crystals, solvent and crystallization agents are diamagnetic. For albumin and DNA, the magnetic field gradients, $B(dB/dy)$ necessary for floating crystals are estimated to be 972 and 808 T2/m, respectively. Floating a crystal by applying a magnetic field gradient is the effective method of damping solute convection during crystal growth on the earth.
