Abstract
A device for moving a magnetic object in a container has two pairs of dipoles grouped around the container. Between the pairs of dipoles a pair of mutually concentrically surrounding quadrupoles is arranged. The dipoles and the quadrupoles are in the form of a Halbach cylinder. In this way, the magnetic object can be moved through the container particularly efficiently.
Claims11
1:
- A device for moving a magnetic object (8) in a container (7), having dipoles (1-4) grouped around the container (7) and a quadrupole (5, 6), wherein the magnetic fields of the dipoles (1-4) and of the quadrupole (5, 6) can be moved relative to one another, wherein two pairs of dipoles (1-4) are arranged in different planes, at a distance from one another, and wherein two quadrupoles (5, 6) are arranged in a plane between the planes of the two dipoles (1-4).
2:
- The device according to claim 1, wherein magnets are arranged in Halbach cylinders in order to generate the dipoles (1-4) and the quadrupoles (5, 6), and enclose a space (18) intended for the container (7).
3:
- The device according to claim 1, wherein two Halbach cylinders, each having magnets for generating the dipoles (1-4) and/or the quadrupoles (5, 6), are arranged concentric to one another.
4:
- The device according to claim 2, wherein the Halbach cylinders, which enclose one another concentrically, can be moved relative to one another.
5:
- The device according to claim 2, wherein the dipoles (1-4) and quadrupoles (5, 6), which are configured as Halbach cylinders, have a drive apparatus (10), in each instance, and are mounted so as to rotate relative to one another.
6:
- The device according to claim 4, wherein a carriage (13) for holding the container (7) that contains the object (8) can be moved relative to the dipoles (1-4) and the quadrupoles (5, 6), and that wherein a relative movement direction of the carriage (13), relative to the dipoles (1-4) and the quadrupoles (5, 6), is arranged parallel to the axis of rotation of the Halbach cylinders.
7:
- The device according to claim 6, wherein the carriage (13) can be displaced parallel to the axis of rotation of the Halbach cylinders.
8:
- The device according to claim 1, wherein the magnetic object (8) is arranged in a probe (14) that is configured to be introduced into a human body or an animal body.
9:
- The device according to claim 8, wherein the probe (14) has at least one sensor (15) for capturing data.
10:
- The device according to claim 8, wherein an induction coil (16) is arranged in the probe (14).
11:
- The device according to claim 1, wherein the magnetic object (8) is configured as a permanent magnet.
