Abstract
The invention discloses a simple spring balance teslameter, relates to the field of physical quantity measurement, and in particular to the rough estimation of a physical quantity. A teslameter is relatively complex and heavy and is not easy to move; and the probe is fine and easy to break. In order to rapidly and conveniently measure the approximate size of a magnetic field, a spring balance is adopted to measure the force of the magnetic field, and the magnitude of the magnetic field is judged according to the magnitude of the force. The technical scheme is that a stainless steel disc is arranged at the front end of the spring balance; the disc is contacted with the surface of a magnet; the spring balance is drawn till the stainless steel disc is disassociated from the surface of the magnet; the numerical value of the force at the moment of dissociation is recorded, i.e. the maximum value observed on the spring balance. The action force between the magnetic field and the stainless steel disc is F=B*B*S/ (2u0), wherein B is the magnetic sensing strength; S is the contact area; u0 is the vacuum permeability; and F is the force. The simple spring balance teslameter has the beneficial effects of simple, rapid and convenient measurement, low cost and movement convenience.
Description
Technical field
The present invention relates to the guestimate of the field of measurement of physical quantity, particularly physical quantity.
Background technology
The teslameter more complicated, heaviness is difficult for moving.Probe is meticulousr, fractures easily.
Spring balance can ergometry size, accurately general.
There is very big relation in magnetic field with distance, and the nearly magnetic field of distance is strong, a little less than the distance magnetic field, so most applications only need know that the approximate size in magnetic field is just enough.
Summary of the invention
In order to realize the approximate size in measurement magnetic field, quick and convenient ground, the present invention adopts spring balance to measure magnetic field force, judges the magnetic field size by the size of power.
The present invention realizes that the technical scheme that goal of the invention adopts is: the front end at spring balance is arranged a stainless steel disk; Disk contact magnet surface; Draw high spring balance and break away from magnet surface up to the stainless steel disk, record breaks away from the numerical value of force of the breath, just observed maximal value on the spring balance.
Acting force between magnetic field and the stainless steel disk is F=B*B*S/ (2u0), and wherein B is the size of magnetic induction density, and unit is a tesla, is called for short the spy, because tesla of unit is bigger, and Gauss also commonly used; S is a contact area, and u0 is a permeability of vacuum, and F is the size of power.
Because power is directly proportional with area, becomes quadratic relationship with magnetic induction density, so scale is heterogeneous, the diameter by the stainless steel disk is the 2mm scale earlier; Design 3 stainless steel disks, its diameter is 2mm, 6.3mm, 20mm, represents three ranges, and each range differs 10 times.
The invention has the beneficial effects as follows: measure simple and fast, with low cost, conveniently moving.
