Abstract: The invention relates to a method for conditioning a suspension containing magnetizable particles, wherein suspension containing the magnetizable particles is guided through a gap (3) in order to bring about shear strain in the suspension containing the magnetizable particles. A magnetic field is applied in the gap (3) such that suspension containing the magnetizable particles is sheared in the presence of the magnetic. The invention further relates to a device for conditioning suspensions containing magnetizable particles, comprising at least one gap (3) through which the suspension containing magnetizable particles flows, in order to apply a shear force to the suspension containing magnetizable particles. The device further comprises at least one magnet for generating a magnetic field in the at least one gap (3).

Abstract: The invention relates to a rheometer, comprising a rotatable shaft (1), to which a rotor plate (2) is fixed, and a measuring device (10), for measuring torques exerted on the rotor plate (2) by a substance under investigation during a rotation of the shaft (1), wherein a first measuring gap (5), for accommodating the substance (6) under investigation, is formed between a first side (3) of the rotor plate (2) and a first shear surface (4) and a second measuring gap (9), for accommodating the substance (6) under investigation, is formed between a second side (7) of the rotor plate (2) away from the first and a second shear surface (8). The rheometer contains a magnet for generating a magnetic field in the first and second measuring gaps (5, 9).
