Abstract
The utility model is a kind of magnetic line of force plane distribution and dynamic change demonstration instrument, and principal feature holds some iron filings in a transparent airtight container; Arrange one block of magnet at the central part of this container, magnet can sway; When rotor magnet, can there is corresponding change in the distribution of the iron filings in magnet surrounding container and sensing, thus show the distribution of the magnetic line of force and point to the occurrence dynamics change with magnetic pole rotation; The container of magnet and splendid attire iron filings forms an entirety, and magnet the two poles of the earth line can pivot 360 degree.
Description
Technical field
The utility model relates to a kind of physics teaching teaching aid, especially can demonstrate the instrument of magnetic line of force distribution and dynamic change.
Background technology
At present, known magnetic line of force demonstrator has two classes: (1) magnetic line of force plane distribution demonstration device, principal feature places iron filings on a glass, magnet is placed under glass plate, when demonstration, need to prepare magnet and iron filings respectively, and magnet and iron filings do not form an entirety, inconvenient.(2) magnetic force line stereo distribution demonstration device, principal feature is splendid attire transparency liquid in a transparent vessel, liquid is evenly equipped with little buoyancy aid, magnet immerses liquid, and namely the fluid space of little buoyancy aid near magnet be arranged in line, demonstrates out the three-dimensional distribution situation of the magnetic line of force, when demonstration, need to prepare liquid, little buoyancy aid, magnet respectively, and above-mentioned article do not form an entirety, inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of magnetic line of force plane distribution demonstration instrument, and it can not only demonstrate magnetic line of force plane distribution can also show magnetic line of force respective change according to the change tread of pole orientation.
The purpose of this utility model is achieved in that and holds some iron filings in a transparent airtight container; Arrange one block of magnet at the central part of this container, magnet can sway 360 degree, when rotor magnet, causes the distribution of the iron filings in container and sensing that corresponding change can occur, thus shows distribution and the dynamic change thereof of the magnetic line of force.
Owing to adopting such scheme, the transparent airtight container of magnet and splendid attire iron filings forms an entirety, and magnet the two poles of the earth line can pivot 360 degree, causes the distribution of the iron filings in container and the change of sensing, embodies distribution and the dynamic change thereof of the magnetic line of force.
