Method for removal of water from a web W being formed. In the method a drainage pressure is created in the web forming part of the paper machine or a drainage pressure that is produced in some other way is made more effective. In the method one or more magnetic fields B are employed with which a force effect is created that promotes drainage of web W. By mean of magnetic field B or fields a force effect is directed against the electrically conducting wires 10, 20, 21 and with said force a pressure drop is created between two opposite wires 10, 20, 21 that removes the water from web W.
