Abstract

The invention relates to a magnetic pendulum and simple pendulum combined experimental instrument, which belongs to the field of basic physic teaching and research instruments. The magnetic pendulum and simple pendulum combined experimental instrument comprises a base, a stand column, an angle indicating device, a simple pendulum device, a magnetic pendulum device, a laser alignment device, a photoelectric detector and the like, wherein an intelligent measuring device is arranged on one side of the base; the stand column and an air track are arranged on the base; the two ends of the air trackare provided with the laser alignment device and a correction plate; the single pendulum device is arranged at the top of the stand column; and the magnetic pendulum device and the angle indicating device are arranged in a chute of the stand column. In the experimental instrument, the single pendulum is combined together with a magnetic pendulum experimental instrument, so that two kinds of experiment can be completed by one set of instrument; and a cycloid and a pendulum rod are guaranteed to swing in one plane by adopting laser alignment positioning and pivot angle acoustic image indication, so that the measurement results are more accurate and scientific. The magnetic pendulum and simple pendulum combined experimental instrument solves the problem that the instruments occupy a lot of space because the conventional single pendulum experiment and magnetic pendulum experiment are completed by different experimental instruments, and the problem that the measuring precision of the experiment is low and cannot meet the requirements of physic teaching and researches.

Description

Technical field: [0001] The invention relates to a magnetic pendulum single pendulum comprehensive experimental instrument, which belongs to the field of basic physics teaching and research instruments. Background technique: [0002] The pendulum is an experimental instrument, which can be divided into simple pendulum and magnetic pendulum according to its type, which can be used to display various mechanical phenomena and even electromagnetic phenomena. Simple pendulum experiment, that is, the experiment of using a single pendulum system to accurately study the mechanical linear and nonlinear motion behavior contained in the mechanical system, or to measure the local gravitational acceleration; although there are many instruments that can complete this experiment, in general It is said that the design and manufacture of the instrument is relatively rough, which is reflected in the unscientific vertical adjustment of the vertical column of the pendulum, the inconvenient use ...
