The specification of a wide of bracket base is corresponded, it is ensured that back-shaped support fell after level, branch is fixed by back-shaped support lateral strut
Support.
In above-mentioned technical proposal, on the rack beam precession of the bush whorl of symmetrical 2 magnetic heads it is maximum away from
From consistent and consistent with tape measure value.Ensure that magnetic head precession distance is consistent with tape measure value.The back-shaped support be by
The soft magnet of one entirety is processed, or is assembled by the tight fit of same soft magnet Precision Machining.The hollow sleeve
Cylinder is made up of soft magnet；The magnetic head is divided into different specifications according to the diameter dimension size of its magnetic strength or magnetic head.
The purpose of the present invention is to be placed in parallel the small-sized magnetic field of generation using two pieces of small-sized circular magnets, and by magnet
Both sides add distance between indicating the adjustable spiral of size to regulate and control magnet, so that distance between by regulating and controlling magnet, realizes to magnetic field
The regulating and controlling effect of intensity.Realize make it is a kind of suitable for laboratory it is small-sized, can small range produce controlling magnetic field field intensity
Magnetic field instrument.
The technology of the present invention feature is easy to operate and has professional.The present invention has following beneficial effect：（1）It is easy to make
Simply, it is with low cost.（2）It is professional stronger.（3）Distance between by regulating and controlling magnet, can quantify the tune realized to magnetic field intensity
Control.
