Abstract
The utility model relates to en experimental device for Lenz law in physical teaching, in particular to a small and convenient experimental instrument, applicable to demonstrate whirlpool magnetic damp and the model can be widely used in physical teaching experiment. Lenz law is very important in physical teaching with the demonstration competed by a whirl pool and magnetic damp. Since the prior experimental instrument bulk is large, to demonstrate in classrooms is not easy for teachers. So a small and convenient experimental device is designed that: an end of a spring on the shell is suspended under the demonstration instrument bracket while the other end of the spring is connected with an iron block with a thin iron bar, and a magnetic is under the iron block. The utility model has the advantages that no electricity is used for the device to show experiments vividly, the model is helpful to study of physical rules and concept, has low cost and is easy manufacture for promotion further.
Description
Technical field
The utility model relates to the experimental provision of Lenz law in a kind of physics teaching, particularly relates to the experimental apparatus that a kind of volume is little, be easy to carry, be used to demonstrate the eddy current magnetic damping, can be widely used in the physics teaching experiment.
Background technology
Lenz law is considerable in physics teaching, and its demenstration method is finished with eddy current and magnetic damping mostly.But the existing most volume of experimental apparatus that is used to demonstrate the eddy current magnetic damping is bigger, is not easy to the teacher and is carried to class demonstration, so we have designed the little portable experimental provision of a kind of volume.
Summary of the invention
The purpose of this utility model is the technical scheme that discloses the multi-functional demonstrator structure of the little portable magnetic damping of a kind of volume.
The technical solution of the utility model: the multi-functional demonstrator of magnetic damping, its characteristics are: place an end of a spring of shell to be suspended on cord below the support of demonstrator, the other end of spring links to each other with iron block with thin iron staff, is magnet below the iron block.
The beneficial effects of the utility model: we have added spring oscillator mechanism in this demonstrator, this device does not need, auxiliary facilities such as power supply have been saved, experimental situation there is not specific (special) requirements, and can demonstrate a plurality of experiments, phenomenon is fairly obvious, is very beneficial for student's learning physics rule, deepens the understanding to physical concept.
In addition, this installation cost is lower, makes easily, is very beneficial for extensive popularization.
