Numerical analysis of static magnetic field force for probe of online magnetic flux leakage detection system was conducted by combining ANSYS and Virtual work method. The result shows that combination of ANSYS and virtual work method could accurately calculate the static magnetic field force between the probe and the drill pipe. In addition, numerical solution in 3D model could reduce the calculation error caused by nonlinear distribution of magnetic induction B between the probe and the cylindrical surface of drill pipe. What's more, the graphs of static magnetic field force were obtained by the different thickness of the yoke and air gap thickness between the probe and the drill pipe. The graphs show that the static magnetic field force changed linearly with yoke thickness. However, it changed nonlinearly with the air gap thickness between the probe and the drill pipe. It can be concluded that the effect for static magnetic field force of latter was greater than that for static magnetic field force of former
