Technical field
The present invention relates to a kind of application methods of the small-sized instrument for generating small range magnetic field, are a kind of from using
Be suitable for laboratory use and provide can appropriate regulation small-sized magnetostatic field experimental provision application method.
Background technology
The mankind have long ago found that magnetic field, and China ancients have found and manufactured compass using magnetic field at first, promote
The rise of world's navigation.Since Ampere in 1820 produces first electromagnet in the world, magnetic field just becomes the modern times
One basic tool of scientific research, after high-intensity magnetic field especially is applied to scientific research, there are many new phenomenons in scientific circles
And new effect, and thus produce many new concepts and new thought.But most artificial field is all electromagnetic field now, mesh
Before, the research direction of magnetic instrument is the huge magnetic field of the large-scale high intensity of manufacture, but for some needs in laboratory as far as possible
The fine experiment of exclusive PCR, need low-intensity, magnetostatic field experiment in, for example, the reaction compound experiment of new material, plant species
Son, the differential growth experiment under plant magnetic field, the magnetic field induction experiment of living cells etc., the electromagnetic field instruments of these recent studies ons without
Method uses.So, it is now desired to it is a kind of suitable for laboratory it is small-sized generate small range, fine-tuning magnetic field small instrument
Device.
Therefore, it is necessary to one kind to be suitable for laboratory use, and provide can appropriate regulation small-sized magnetostatic field experimental provision and
Application method.
Invention content

Surface be machined with the embedding column of lateral strut and the embedding column of bracket base, be able to the groove that embedded back-shaped stent lateral strut corresponds to processing
In and back-shaped bracket base correspond to processing groove in.The height of the back-shaped stent lateral strut and the wide a of back-shaped bracket base
Specification correspond, ensure that back-shaped stent is horizontal after falling.It is characterized in that, operating procedure is as follows.
The first step installs magnetic head；According to the magnetic field size of requirement of experiment, selection a pair of magnetic field intensity is of the same size, end
The opposite magnetic head of head plane magnetic pole；The magnetic head that first one has been chosen is mounted on back-shaped one rack beam of stent, is revolved completely
Length into magnetic head to hollow sleeve is all inserted on rack beam, then another magnetic head chosen is mounted on back-shaped branch
On another rack beam of frame.Then, while magnetic head is fallen back at " 0 " zero graduation of two scales.At this point, two magnetic heads
Transverse plane is tightly affixed and is combined.
Second step, adjustment, according to the size of laboratory sample and the size of magnetic field requirements, two magnetic heads of knob, make two respectively
A magnetic head is drifted apart from, and to after suitable phase spacing, 2 magnetic heads are fixed to the identical scale of two scales.Scale is recorded to read
Number, looks into the corresponding magnetic field intensity of scale.That is, the leaf sight range being separated by per a pair of of magnetic head of device, we survey in advance
Magnetic field intensity has been measured, has been depicted as table, has been used convenient for experiment.Or in next step, the magnetic field at direct determination sample position is strong
Degree.
Third walks, and places sample experiments；According to laboratory sample size, vertical apparatus for placing is selected；Or selection is horizontal positioned
Device matches the specification of back-shaped stent lateral strut and the wide a of back-shaped bracket base.Test specimen is put between 2 magnetic heads
In gap, according to setting time length, the effect of Observe and measure test specimen.During the experiment, can continue to 2 magnetic heads of adjustment it
Between distance, change magnetic field intensity.
In above-mentioned technical proposal, used device, the sleeve spiral shell of symmetrical 2 magnetic heads on the rack beam
Line, thread pitch is consistent, and precession maximum distance is consistent, and tape measure value is consistent.It ensure that magnetic head precession distance is surveyed with scale
Magnitude is consistent.The back-shaped stent is to be process by the soft magnet of an entirety or tight by same soft magnet Precision Machining
Close fit assembles；The hollow sleeve is made of soft magnet；The magnetic head is according to its magnetic strength or the diameter of magnetic head
Size is divided into different specifications.
The purpose of the present invention is be placed in parallel to generate small-sized magnetic field, and by magnet using two pieces of small-sized circular magnets
Both sides are plus indicating the adjustable spiral of size to regulate and control distance between magnet, so as to by regulating and controlling distance between magnet, realize 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 generate controlling magnetic field field strength
Magnetic field instrument.
