A first invention relates to a measuring arrangement, which includes a coil arrangement (11) arranged to create a magnetic field (B) in order to measure a sample (14) to be arranged in connection with it, and electronics (13) connected to the coil arrangement for creating a magnetic field (B) using the coil arrangement. The coil arrangement includes at least one flat coil (12), the coil geometry of which is arranged to be changed in the direction (K) of the plane defined by the flat coil, in order to create a spatially changing magnetic field for measuring the sample, and the measuring arrangement (10) includes means (24) for changing the position of the sample and the coil arrangement relative to each other in order to change the magnetic field affecting the sample. In addition, this invention also relates to a method for measuring a sample. A second invention relates to a disc or a plate with several hollow areas in which at least one sample can be placed. A third invention relates to a device aiming at affecting magnetic particles in the sample. |
