Abstract
A physical experiment teaching instrument-an intelligent 3-dimension magnetic field intellectual measurer that can detect magnetic field three-dimensional component and composite value size thereof instantly in one time contains a three-dimensional magnetic survey probe composed of three hall components mutually, vertically and separately arranged and an instrument host. The three-dimensional magnetic survey probe is connected with the instrument host by a wire. The three hall voltage values obtained by the three-dimensional magnetic survey probe around the magnetic field to be measured are proportional to the components Bx, By, Bz of magnetic field along the directions of X, Y and Z. The value of each component of the magnetic field and the composite value size of each component can be shown in figures by a measurement amplifying circuit and a computer processing in the instrument host.
Description
Affiliated technical field
The utility model relates to a kind of physics experiment teaching instrument of measuring magnetic field, especially can measure the intelligent three-dimensional detection of magnetic field instrument of the three-dimensional component and the composite value size thereof in magnetic field moment once.
Background technology
In the method in physical detection magnetic field, generally the method for Cai Yonging is to carry out magnetic-field measurement with single Hall unit at present.When unknown magnetic field being measured, need to look for the maximal value of the Hall voltage of Hall unit generation, thereby judge the direction in magnetic field with azimuthal method between change Hall unit and magnetic field with this method.Therefore, generally be usually used in the one dimension magnetic field of known direction is measured with single Hall unit, and when the magnetic field of unknown direction measured, not only more time-consuming also very inconvenient with said method, and when the size and Orientation in magnetic field often changes, can be difficult more in the operation.
Summary of the invention
In order to measure the size and Orientation in magnetic field in moment, the utility model provides a kind of physical experiment apparatus that can measure the size and Orientation in magnetic field moment once.During use, click the measurement button of instrument, just can be on instrument demonstrate the instrument probe loca respectively and measuring at that time the three-dimensional component in magnetic field and the size of composite value thereof with numeral.Calculate or mapping by vector again, just can obtain at the magnetic field size and Orientation of measuring the loca of popping one's head at that time.
The main technical schemes that its technical matters that solves the utility model adopts is: constitute a three-dimensional magnetic probe of surveying with three orthogonal and independent Hall units of placing.Definition is respectively " X ", " Y ", " Z " coordinate axis by the normal of these three Hall unit principal planes, and then these three Hall units obtained Hall voltage when measuring will be directly proportional with component Bx, By, the Bz of magnetic field on " x ", " Y ", " Z " these three directions respectively.After measuring the processing of amplifying circuit and computing machine in the instrument host, demonstrate the value of each component of magnetic field and the size of three component composite values respectively with regard to available digital.
The beneficial effects of the utility model are can measure once moment at the magnetic field size and Orientation of measuring the loca of popping one's head at that time.Simultaneously in the Experiment of College Physics experiment of student's vector compound training being provided a kind of instruments used for education of practicality.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the three-dimensional three-dimensional of surveying magnetic probe of the present utility model is surveyed the magnetic synoptic diagram.
Fig. 2 is with measurement performance figure of the present utility model.
In Fig. 2: 1. the three-dimensional magnetic probe of surveying, constitute by three rectangular-shaped Hall units, 2. instrument host is 3. treated measuring magnetic field.
Embodiment
In Fig. 1, three rectangular-shaped Hall units are orthogonal, independent to be placed, and the normal by three Hall unit principal planes is defined as " X ", " Y ", " Z " coordinate axis respectively, establishes magnetic field
Component on these three coordinate axis is respectively Bx, By, Bz, and then the Hall voltage on three Hall units just is directly proportional with corresponding magnetic-field component respectively, through the processing and amplifying of instrument with calculate and just can learn three component values in magnetic field.
In embodiment illustrated in fig. 2, after three-dimensional survey magnetic probe (1) and instrument host (2) connect, when near treating measuring magnetic field (3), measuring magnetic field, the measured Hall voltage signal of each Hall unit is sent into instrument host respectively by electric wire in the three-dimensional survey magnetic probe, through the processing of amplifying circuit and computing machine, the correlation measure with magnetic field shows with numeral respectively at last.
Claims (1)
1. intelligent three-dimensional detection of magnetic field instrument, this instrument comprises a three-dimensional magnetic probe and the instrument host two parts surveyed, it is characterized in that: the three-dimensional magnetic probe of surveying is to be made of three orthogonal, independent Hall units of placing, and the three-dimensional magnetic probe of surveying links to each other with instrument host by electric wire.
