Abstract

The invention discloses an electromagnetic ejection system. The electromagnetic ejection system comprises a base, wherein the base is internally provided with a control circuit, the base is provided with a base tube, a first button and a second button, the base tube is internally disposed, an outer wall of the base tube is wound by an electromagnetic coil, the control circuit comprises a battery pack, a triode, a first resistor, a second resistor, a transformer, a diode, a storage capacitor, a voltage-regulator tube and a silicon controlled rectifier, the storage capacitor is charged through the second button, the silicon controlled rectifier is triggered through utilizing the first button, the storage capacitor is made to discharge electrical energy to an electromagnetic coil, and therebyejection of iron beads is completed. The electromagnetic ejection system is advantaged in that teaching in joy is achieved, students are helped to better understand the work principle of an electromagnetic gun, and the electromagnetic ejection system can be applied to teaching.

Description

technical field [0001] The invention relates to the technical field of model teaching aids, in particular to an electromagnetic ejection system. Background technique [0002] The force experienced by moving charges in a magnetic field is called Ampere's force, which is the force that a magnetic field exerts on moving charges. This principle is used in the military to manufacture electromagnetic guns. Electromagnetic guns have the advantages of fast firing rate and long range. At the same time, since gunpowder is not required, compared with gunpowder-launched shells, it can greatly save space and greatly reduce costs. [0003] In order to allow students to better understand the working principle of electromagnetic guns, many schools have produced some model teaching aids, but the existing model teaching aid systems are complicated and rigid, and it is not easy to arouse students' interest. Contents of the invention [0004] In order to solve the problems existing in the pr...
