The invention relates to a method for separating out a substance dispersed or dissolved in a first liquid by using the following steps:

• a) adding magnetizable particles to the first liquid, so that the substance is adsorbed on the particles;
• b) immersing a rod consisting of a soft magnetic material into the first liquid;
• c) magnetizing the rod along its longitudinal axis with an exciter coil, thus causing the particles with the adsorbed substance to be deposited on the rod;
• d) pulling the rod with thereon deposited particles from the first liquid while the rod is still magnetized;
• e) immersing the rod into a second liquid;
• f) turning off the exciter coil and washing off the particles deposited on the rod in the second liquid.

Also proposed is a magnet separator for realizing the method.
