Problems solved by technology

[0002] Due to the small size and weak magnetism of magnetic nanoparticles, they can be widely used in different fields. For some specific fields, it is necessary to inject magnetic nanoparticles into a specific position of the solution, and then apply an external alternating magnetic field outside. Under the action of an alternating magnetic field, the alignment direction of the magnetic domains in the magnetic nanoparticles will also change alternately with the direction of the magnetic fie

Abstract

The present invention provides a magnetic particle control device based on a three-dimensional magnetic field. The device comprises a support frame, an insulating working chamber and six magnetic conductive rods. The support frame comprises a rectangular frame structure, each side of the rectangular frame structure is provided with a fixed hole. The insulating working chamber is arranged in the rectangular frame structure. One end of each of the six magnetic conductive rods abuts against the insulating working chamber. The six magnetic conductive rods are sleeved by pulse coils which are sleeved by polarization coils, the polarization coils are clamped in the fixed holes. The pulse coils are provided with wiring terminals, and the polarization coils are provided with wiring conductive columns which are connected to the anode and cathode of a power supply through conductive wires. According to the device, a three-dimensional timing maintaining constant orientation magnetic field and a pulse magnetic field can be combined so as to realize the deep aggregation of magnetic nanoparticles in the insulating working chamber.

Description

technical field [0001] The invention relates to the technical field of magnetic field control, and more specifically, to a magnetic particle control device based on a three-dimensional magnetic field. Background technique [0002] Due to the small size and weak magnetism of magnetic nanoparticles, they can be widely used in different fields. For some specific fields, it is necessary to inject magnetic nanoparticles into a specific position of the solution, and then apply an external alternating magnetic field outside. Under the action of an alternating magnetic field, the alignment direction of the magnetic domains in the magnetic nanoparticles will also change alternately with the direction of the magnetic field. During the rotation change process, the magnetic domains collide and rub against each other, thereby generating heat. Through this hysteresis, heat is generated. The first condition for realizing the above-mentioned heating device is to be able to move the magnetic...
