Abstract
The invention provides a magnetic damping pendulum which comprises a base plate. Two mounting plates are mounted on the base plate at interval. An adjusting screw is fixed on each mounting plate through a thread. A magnet is disposed at the tail of each adjusting screw. A magnetic field is formed between the two magnets. A sheet-shaped aluminum pendulum body is disposed in the magnetic field and hung on the groove of a crossbeam. A comb-shaped aluminum pendulum body hung in the groove in the other end of the crossbeam. The crossbeam is mounted on the base plate through screws.
Description
Technical field
The present invention relates to a kind of instruments used for education, especially relate to a kind of magnetic damping pendulum of physics teaching experiment, belong to instruments used for education field.
Background technology
The magnetic damping pendulum of current physics teaching experiment is of a great variety, but its complex structure effect is also obvious not.
Summary of the invention
The object of this invention is to provide a kind of easy magnetic damping pendulum meter device, this instrument not only structure is simple, rationally distributed, and experiment effect is obvious.
A kind of magnetic damping pendulum meter device of the present invention, comprise base plate, on base plate, interval is provided with two installing plates, each installing plate is fixed with set screw by screw thread, and set screw afterbody has magnet, forms magnetic field between two magnet, flaky aluminum pendulum is provided with in magnetic field, flaky aluminum swinging hanging is on the groove of crossbeam, and be hung with pectination aluminium pendulum in the other end groove of crossbeam, described crossbeam is arranged on base plate by screw.
Beneficial effect of the present invention is: structure is simple, and experiment effect is obvious, and put and pectination aluminium pendulum by the flaky aluminum be suspended on crossbeam, swing by, cutting magnetic line in magnetic field, the magnetic field that pectination aluminium pendulum produces eddy current makes swing speed have significant change.
Accompanying drawing explanation
Fig. 1 is the structural representation of magnetic damping of the present invention pendulum;
Fig. 2 is flaky aluminum pendulum structural representation;
Fig. 3 is pectination aluminium pendulum structural representation.
In figure: 1. base plate; 2. installing plate; 3. set screw; 4. magnet; 5. flaky aluminum pendulum; 6. crossbeam; 7. pectination aluminium pendulum.
Embodiment
As shown in Figure 1, magnetic damping pendulum of the present invention comprises base plate 1, on base plate 1, interval is provided with two installing plates 2, each installing plate is fixed with set screw 3 by screw thread, and set screw afterbody has magnet 4, forms magnetic field between two magnet, flaky aluminum pendulum 5 is provided with in magnetic field, flaky aluminum pendulum 5 is suspended on the groove of crossbeam 6, and be hung with pectination aluminium pendulum 7 in the other end groove of crossbeam, described crossbeam 6 is arranged on base plate 1 by screw.
Put 5 and pectination aluminium pendulum 7 by the flaky aluminum hung on the cross beam 6, swing by, cutting magnetic line in magnetic field, the magnetic fields that pectination aluminium pendulum 7 produces eddy current make swing speed have significant change.
