Free Surface Behavior under Alternating and Static Magnetic Field

摘要：

　　In order to reasonably control the free surface oscillations,by using GaInSn low-melting alloy,the fluctuation and distortion behaviour of metal free surface is investigated under AC magnetic field.By simultaneously superposing DC magnetic field,the damping effect of DC magnetic field on free surface fluctuation is also investigated.In the cylindrical pool,the azimuthal and radial oscillation mode can be found simultaneously due to AC magnetic field.Moreover,the free surface is more stable in square pool than that in the cylindrical pool.Increase coil AC current,the free surface fluctuation is aggravated.A series of surface waves can be observed on free surface with compound magnetic field.Reasonable DC magnetic field can effectively damp the oscillations on the free surface in cylindrical pool.However,the DC magnetic field cannot effectively damp the surface oscillations in square pool.The DC magnetic field has no significant damping effect on the oscillations induced by the lower frequency magnetic force.
