A plurality of elongated magnets are perpendicularly fixed on four rectangular end faces around the middle magnet. The contact polarities of the elongated magnets and the four rectangular end faces around the middle magnet are the same. The permanent magnet device used for Zeeman effect experiments has the advantages of good uniformity, compactness, handiness, simple operation and little effect on electronic system and equipment around. The stability, continuation and adjustability of the magnetic induction intensity and the like can be achieved. The permanent magnet device used for Zeeman effect experiments is applicable to modern physical experiments in universities, and also applicable to relative instruments of the Zeeman effect background technology.
Description
Technical field
The present invention relates generally to the magnet field, relates in particular to a kind of permanent magnet device for zeeman effect experiment.
Background technology
At present, employed strong magnetic device generally adopts electromagnet apparatus in the Zeeman effect test, and this system comprises the electromagnet main body, stablize the part such as regulated power supply.The electric current that changes solenoid by regulating power supply reaches the purpose that changes magnetic induction density.Has the strong and continuous advantage such as adjustable of magnetic induction density.But because need additional supply, have more intense electric current in the solenoid, have potential safety hazard, current stability in the coil directly has influence on the stability of magnetic field intensity, because electric current is arranged, be easy to strong electric field and form interference, disturb Zeeman effect so that have Stark effect in the test, affect the performance of experimental result and Zeeman effect buckle back scape technology instrument.This system and cost are higher, and manufacture difficulty is larger, and whole system is heavy, use inconvenient.And other permanent-magnet systems will produce high-intensity magnetic field, and the volume that needs is larger, and weight is large, because the magnet volume is larger, easily near other electronic systems and equipment is exerted an influence in the use.
Summary of the invention
The permanent magnet device that is used for zeeman effect experiment that the purpose of this invention is to provide a kind of easy, high stability, the magnetic field homogeneity of this device is good, and volume is little, lightweight, simple to operate, easy to use, cost of manufacture is low, can add the magnetic shielding shell if needed, reduce magnet to the interference of electronic system and equipment etc. on every side, can by regulating magnet between distance realize the series of advantages such as the steady and continuous of magnetic induction density is adjustable.
The present invention is achieved by the following technical solutions:
The permanent magnet device that is used for zeeman effect experiment, it is characterized in that: include polylith magnet, the end face of one of them strip magnet is square, end face is that foursquare strip magnet is as middle magnet, vertically be fixed with respectively polylith magnet on four rectangle end faces around the middle magnet, each strip magnet is identical with the polarity of four rectangle end contacts all around of middle magnet.
The polarity of four rectangle end contacts around described each strip magnet and the middle magnet can be the S utmost point simultaneously, can be the N utmost point simultaneously also.
Described each strip magnet is selected rubidium iron boron strong magnetic material.
Described each strip magnet uses and does not disturb the aluminium alloy firmware of magnetic to fix by after making up, the effect that the magnetic field intensity of an end face of magnet strengthens in the middle of reaching.
Described system if need magnetic shielding, can add the magnetic shielding shell after using the aluminium alloy firmware fixing, reduces magnet system to the interference of electronic system and equipment on every side.
Principle of the present invention is:
The magnetic field intensity of middle magnet strengthens: according to the flux path principle, when each strip magnet and end face be foursquare strip magnet around the polarity of four rectangle end contacts when being the S utmost point simultaneously, the S utmost point is the strongest; When each strip magnet and end face be foursquare strip magnet around the polarity of four rectangle end contacts during simultaneously for the N utmost point, the N utmost point is the strongest.
Advantage of the present invention is:
Magnetic field homogeneity of the present invention is good, and magnetic field intensity is large, and small volume and less weight, simple to operate, little to surrounding environment influence, can realize the series of advantages such as the steady and continuous of magnetic induction density is adjustable, can be used for colleges and universities' Experiments of Modern Physics, also can be used in the pertinent instruments of Zeeman effect buckle back scape technology.
