Description
Technical field
The utility model relates to the science and education Instrument technology field, is specifically related to the three-dimensional magnetic field demonstrator that uses when a kind of physical electromagnetic is imparted knowledge to students.
Background technology
At present; The three-dimensional magnetic field demonstrator of prior art generally comprises transparent vessel, magnet, transparency liquid (most is oil-based liquid) and is immersed in the iron powder in this liquid; Transparent vessel is the closed container that transparent material is processed; Transparent fluid of splendid attire and iron powder in the transparent vessel, magnet (like horsehoe magnet, cylindrical magnetic iron or relative two column type magnet) outerwrap transparent plastic are fixed on the transparent vessel center and immerse liquid, and iron powder is under the effect in magnetic field; Just automatically outside magnet parcel plastics, be arranged in a ball of string, promptly in the fluid space around the magnet, simulate the three-dimensional distribution situation in magnetic field.
There is following defective in this solid magnetic field demonstrator: (1) transparent vessel is a closed container, so outer shape that can only the demonstration magnet surrounding magnetic field can not be demonstrated the inner magnetic induction line distribution situation in magnetic field; (2) it is big from weight to fill with the transparent vessel of liquid, receive the collision cracking easily and make leak of liquid, thereby lose demonstration effect, contaminated environment, and oil-based liquid also initiation fire is dangerous easily, bring potential safety hazard for the transportation and the use of this solid magnetic field demonstrator.
The utility model content
The utility model technical matters to be solved provides a kind of three-dimensional magnetic field demonstrator; This solid magnetic field demonstrator can the demonstration magnet surrounding magnetic field outer shape; Can demonstrate the inner magnetic induction line distribution situation in magnetic field again, and long service life, transportation and safe in utilization.
For addressing the above problem, the utility model provides a kind of three-dimensional magnetic field demonstrator, comprises transparent vessel, magnet, iron powder.Said transparent vessel is made up of first obturator that is hinged and second obturator; First madial wall of first obturator and second madial wall of second obturator are the plane; First madial wall and second madial wall fit to together after the folding each other between first obturator and second obturator, first obturator and second obturator altogether.First madial wall and the second madial wall location matches place respectively are provided with at least one storage tank; The shape of storage tank is identical with the shape that magnet is divided back half magnet that forms equally along pole orientation; Said magnet is arranged in the storage tank of first obturator; Magnet has half to place in the storage tank; First obturator and second obturator second half of back magnet altogether just can place in the storage tank of second obturator, and this moment, second madial wall of first madial wall and second obturator of first obturator was still fitted intactly, and magnet is positioned at the inside of the transparent vessel that first obturator and second obturator form.Said iron powder is loaded in first obturator, second obturator.
Said first obturator is identical, measure-alike with the second obturator shape.
The iron powder amount of said first obturator, second obturator inside is identical.
Said magnet is bar magnet or U magnet or cylinder-shaped magnet.Certainly, also can be qualified other shape magnet.Said magnet is the strong magnetic of neodymium iron boron.
The method of application of this solid magnetic field demonstrator is: shake after first obturator and second obturator are lumped together; Then iron powder is because the action of a magnetic field of magnet just has been drawn onto magnet on every side; Around magnet, form the outer shape in magnetic field; Then first obturator and second obturator are opened; Iron powder in second obturator is not owing to there is the sucking action of magnet to be scattered again, and the iron powder in first obturator is because the existence of magnet still keeps the shape that is attracted, and first madial wall that sees through first obturator just can be seen the magnetic induction line distribution situation that magnetic field is inner.
After adopting above structure; The utility model compared with prior art; Have the following advantages: can be drawn by above analysis, the outer shape that the three-dimensional magnetic field of the utility model demonstrator can the demonstration magnet surrounding magnetic field can be demonstrated the inner magnetic induction line distribution situation in magnetic field again.And iron powder that should solid magnetic field demonstrator directly places the inner space of transparent vessel, is not immersed in the liquid, so iron powder is not easy to get rusty, service time is long.Owing to only use dried iron powder in the container, do not add liquid again, whole demonstration device weight saving is difficult for breaking, and is convenient to transportation and preservation.This has also effectively prolonged the serviceable life of three-dimensional magnetic field demonstrator.
