Static deformation of the free surface is investigated for a thin magnetic fluid layerunder axisymmetric magnetic field. Special attention is paid to the case that the effectof the surface tension is much larger than that of the gravity (i.e. the Bond number,Bo is very small). It is shown analytically that in the limit Bo=O the tail of the elevation of the surface decreases as - log r away in the radial direction as r= c0, irrespec-tive of the form of the applied field. Numerical calctulations for the case of the dipolefield sustain the asymptotic result.[magnetic fluid, ferrofluid, Bernoulli equation, xnagnetic Bond number, drag lI reductionl
