An experiment of wave making using ferrofluid was carried out. The visualized wave pattern shows that the the angle between the wave crest line and the rail center is larger as the gradient of the magnetic field increases. It is possible to change Froude number even with same model size and also with same speed by controlling the gradient of magnetic field in ferrofluid.
