A device for stirring a liquid or a granular material comprising a stirring agitator, a rotating drive shaft for rotating the stirring agitator, a rotating drive shaft for rotating the stirring agitator, a stationary axle extending in an essentially vertical direction about which the stirring agitator is adapted to rotate, and a transfer arrangement for contactless transfer of rotation of the drive shaft to the stirring agitator. The device has a center axis around which the stirring agitator and the drive shaft are adapted to rotate, and means for generating a magnetic force exerting an upwardly directed force component on the stirring agitator. The means for generating a magnetic force comprises a first element arranged in a stirring agitator and a second element associated with the stationary axle. At least one of the first element and the second element comprises a permanent magnet. At least one of the first element and the second element is arranged such that the center axis extends through the first element and/or the second element.
