Abstract
A kind of small-sized multipurpose multiple-using magnet, symmetrically structure, yoke has two symmetrical symmetric arms, has screwed hole in the center of symmetric arms; Magnetic pole post has the screw thread matched with yoke screwed hole, one end of magnetic pole post is equipped with adjusts field swing handle; Two magnetic pole posts are screwed in by screwed hole respectively outside two of yoke symmetric arms, the tune field swing handle of magnetic pole post one end is positioned at the outside of yoke symmetric arms, the magnetic pole post other end then stretches into the inner chamber formed inside yoke symmetric arms, the one end entering the magnetic pole post of yoke inner chamber is inhaled even by magnetic force and permanent magnet, the outer end of permanent magnet and outside polar cap are inhaled and are connected, and form air gap between two relative polar caps; Two direct current field sweep coils are arranged on respectively and stretch on two magnetic pole posts of yoke inner chamber, and are connected with adjustable power of direct current by lead-in wire.It is little that the utility model has volume, and stable magnetic field, continuously adjustable feature, can be used for nearly all magnetic resonance experiments.
Description
Technical field
The utility model relates to a kind of magnet, particularly relates to a kind of small-sized multipurpose multiple-using magnet.
Background technology
Magnet is the requisite device of magnetic resonance experiments, and current laboratory is conventional is electromagnet.The features such as electromagnet has magnetic field continuously adjustabe, uniformity better, but equipment is huger, and also stable magnetic field not easily ensures.Permanent magnet exquisiteness is small and exquisite, but magnetic field adjustable extent is less.
Summary of the invention
The purpose of this utility model is to provide a kind of small-sized multipurpose multiple-using magnet, and it is little that this magnet has volume, and stable magnetic field, continuously adjustable feature, can be used for nearly all magnetic resonance experiments.
A kind of small-sized multipurpose multiple-using magnet, comprises magnetic pole post, yoke, direct current field sweep coil, permanent magnet and polar cap.The utility model is structure symmetrically, and yoke is U-shaped, and yoke has two symmetrical symmetric arms, has screwed hole in the center of symmetric arms; Have the magnetic pole post that two structure size are the same, magnetic pole post has the screw thread matched with yoke screwed hole, one end of magnetic pole post is equipped with adjusts field swing handle, and adjusts the diameter of field swing handle to be greater than the diameter of magnetic pole post; Two magnetic pole posts are screwed in by screwed hole respectively outside two of yoke symmetric arms, the tune field swing handle of magnetic pole post one end is positioned at the outside of yoke symmetric arms, the magnetic pole post other end then stretches into the inner chamber formed inside yoke symmetric arms, the one end entering the magnetic pole post of yoke inner chamber is inhaled even by magnetic force and permanent magnet, the outer end of permanent magnet and outside polar cap are inhaled and are connected, air gap is formed, so that the laying of laboratory sample between two relative polar caps; Two direct current field sweep coils are formed by copper conductor coiling on the column type insulated conductor frame of hollow, are arranged on respectively and stretch on two magnetic pole posts of yoke inner chamber, and are connected with adjustable power of direct current by lead-in wire.
Rotate during operation and adjust field swing handle can make the relative movement of magnetic pole post, thus change the spacing of magnetic pole, and then change the field intensity at air gap place.The utility model have employed and changes the size of pole air-gaps and coil electricity regulates the comprehensive tune field method matched, so both remain that permanent magnet volume is little, the advantage of stable magnetic field, make use of again the convenience of the ferroelectric tune field of electromagnetism, and avoid the defect that electromagnet need be equipped with high-power current stabilization stabilized voltage power supply and cooling system usually.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1, magnetic pole post; 2, yoke; 3, direct current field sweep coil; 4, permanent magnet; 5, polar cap.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment
See Fig. 1, a kind of small-sized multipurpose multiple-using magnet, comprise magnetic pole post 1, yoke 2, direct current field sweep coil 3, permanent magnet 4 and polar cap 5.The utility model is structure symmetrically, and yoke 2 is U-shaped, and yoke 2 has two symmetrical symmetric arms, has screwed hole in the center of symmetric arms; Have the magnetic pole post 1 that two structure size are the same, magnetic pole post 1 has the screw thread matched with yoke screwed hole, one end of magnetic pole post 1 is equipped with adjusts field swing handle, and adjusts the diameter of field swing handle to be greater than the diameter of magnetic pole post 1; Two magnetic pole posts 1 are screwed in by screwed hole respectively outside two of yoke 2 symmetric arms, the tune field swing handle of magnetic pole post 1 one end is positioned at the outside of yoke 2 symmetric arms, magnetic pole post 1 other end then stretches into the inner chamber formed inside yoke 2 symmetric arms, the one end entering the magnetic pole post 1 of yoke 2 inner chamber is inhaled even by magnetic force and permanent magnet 4, the outer end of permanent magnet 4 and outside polar cap 5 are inhaled and are connected, air gap is formed, so that the laying of laboratory sample between two relative polar caps 5; Two direct current field sweep coils 3 are formed by copper conductor coiling on the column type insulated conductor frame of hollow, are arranged on respectively and stretch on two magnetic pole posts 1 of yoke 2 inner chamber, and are connected with adjustable power of direct current by lead-in wire.The mild steel that in the present embodiment, yoke 2 selects magnetic permeability high makes, and plays a part to be communicated with magnetic circuit.Magnetic pole post 1 adopts pure iron material to make.Permanent magnet 4 selects NdFeB rare earth permanent-magnetic material to make.
