Abstract
The action and reaction experimental provision of magnetic force, it is made up of support, nut seat, adjusting screw nut, adjusting screw, magnet, iron block, tensiometer, the nut seat is set on the bracket, the adjusting screw nut can be rotated on the nut seat with non-displacement, the adjusting screw is socketed with the adjusting screw nut screw thread, the magnet can the smooth activity between described two adjusting screws, one end of the magnet is equipped with tensiometer, and the tensiometer is hung on the adjusting screw；The iron block also can the smooth activity between described two adjusting screws, one end of the iron block is also equipped with the tensiometer, and the tensiometer is hung on another described adjusting screw.The scale of sign distance is provided with the support between two adjusting screws.The utility model can intuitively show that magnet is equal in magnitude in opposite direction to the attraction of magnet to the attraction of iron block and iron block, and be able to verify that the size of magnetic force and square being inversely proportional for distance.
Description
Technical field
Belong to teaching experimental equipment field, more particularly to physics teaching experiment instrument.
Background technology
Existing active force only verifies the amount of force directly contacted between object with the experiment device for teaching of reaction force
Equal direction is on the contrary, having no the action and reaction specifically for magnetic force and being able to verify that the teaching of magnetic force inverse square relation
Experimental provision.
The content of the invention
The purpose of this utility model is to provide for a kind of action and reaction specifically for magnetic force and is able to verify that magnetic
The experiment device for teaching of power inverse square relation.
Technical solution adopted in the utility model is：The action and reaction experimental provision of magnetic force by support, nut seat,
Adjusting screw nut, adjusting screw, magnet, iron block, tensiometer composition；The nut seat is set on the bracket, the roll adjustment spiral shell
Mother can be rotated on the nut seat with non-displacement, and the adjusting screw is socketed with the adjusting screw nut screw thread, the magnet
Can the smooth activity between described two adjusting screws, one end of the magnet is equipped with tensiometer, and the tensiometer is hung on the tune
Away from screw rod；The iron block also can the smooth activity between described two adjusting screws, one end of the iron block is also equipped with institute
Tensiometer is stated, the tensiometer is hung on another described adjusting screw.It is provided with the support between two adjusting screws
Indicate the scale of distance.
Beneficial effect acquired by the utility model is：Attraction and iron block pair of the magnet to iron block can intuitively be shown
The attraction of magnet is equal in magnitude in opposite direction, and is able to verify that the size of magnetic force and square being inversely proportional for distance.
Brief description of the drawings
Accompanying drawing 1 is the utility model structure diagram.
It is denoted as 1. supports in figure, 2 nut seats, 3. adjusting screw nuts, 4. adjusting screws, 5. magnet, 6. iron blocks, 7.
Tensiometer.
Embodiment
The utility model is described in further details below in conjunction with drawings and examples, with reference to the accompanying drawings shown in 1, this practicality
The action and reaction experimental provision of new involved magnetic force include 1, two, support nut seat 2, two adjusting screw nut 3,
