Description
Technical field
The utility model is related to a kind of electromagnetic experimental device, specially a kind of adjustable solenoid of coil density degree.
Background technology
In electromagnetism, the magnetic field inside current-carrier solenoid is often analyzed and calculated.Theoretical calculation can be obtained：One passes to electric current
The magnetic induction intensity formula of I long straight solenoid internal magnetic field is B=μ0μ in nI, formula0For space permeability, n is solenoid list
The number of turn of institute's coiling on bit length.Therefore, the magnetic field size inside solenoid and the density degree of solenoid institute coiling are close
Cut is closed.For proof theory rule, existing corresponding experimental provision is used to measuring the magnetic field inside current-carrier solenoid, but due to
The density of solenoid institute coiling can not be adjusted in an experiment, it has not been convenient to which checking is when coil density degree changes, helical
The respective change relation of pipe internal magnetic field.
The content of the invention
The purpose of this utility model, is to overcome existing solenoidal disadvantages mentioned above, develops a kind of coil density degree adjustable
Solenoid.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：A kind of coil density degree can
The solenoid of tune, including base, hollow cylindrical tube, helical spring, coil, draw-gear；The hollow cylindrical tube two ends and bottom
Seat fixed connection, the helical spring and the coil are set in hollow cylindrical tube, and one end of helical spring is fixed on sky
In heart cylindrical tube, the other end of helical spring is movable end, can be moved back and forth along hollow cylindrical tube length direction；The coil by
Helix of the insulated conductor along helical spring is constituted with the coiling of helical spring strapped side by side from the beginning to the end；The draw-gear passes through
Drawstring is connected with helical spring movable end, for changing the length of helical spring, driving the density of regulating winding to change
Coil turn in unit length.
The draw-gear is fixed pulley, or is micromachine.
The scale for indicating the coil turn in unit length is additionally provided with the base.
Stretching for the telescopic band moving winding that the utility model passes through helical spring, is conducive to overcoming conventional coiling without bullet
Property, the shortcomings of be inconvenient to stretch, the coil turn in solenoid unit length can be conveniently adjusted in experimentation, is conducive to
Verify solenoid internal magnetic field formula.When helical spring is periodically mobile back and forth, moreover it is possible to by the coil of energization in open circles
Periodically variable magnetic field is produced in column jecket.The utility model is simple in construction, practical and convenient, and the student available for magnetic-field measurement is real
Test.
