The demonstration device has the advantages of simple structure, convenient material drawing, obvious experimental phenomenon, etc. Due to the demonstration device, the electromagnetic gun can be successfully demonstrated by an experiment, students can watch the experiment and obtain perceptual experiences, interest of students in studying physics is greatly raised, and interest of students in exploration after class by a DIY experiment instrument is aroused.
Description
Technical field
The utility model relates to a kind of physics teaching apparatus, specifically is meant a kind of magnetic artillery teaching demonstration device.
Background technology
Magnetic artillery is the Kinetic Kill Weapon that utilizes a kind of advanced person that ELECTROMAGNETIC LAUNCH TECHNOLOGY makes.That powder gas pressure is acted on bullet is different with traditional artillery, magnetic artillery is the acting force that utilizes electromagnetic field in the electromagnetic system, and the time of its effect is much longer, can improve the speed and the range of bullet greatly, thereby, caused countries in the world military strategist and students' concern.
In current physics teaching in secondary school, the curricula that " Faraday's electromagnetic induction law " wherein just arranged, and magnetic artillery is exactly in fact the concrete application of " Faraday's electromagnetic induction law ", therefore in order to improve the visual understanding of student to abstract physical law, deepen their the degree of depth of understanding to " Faraday's electromagnetic induction law ", thereby improve the quality of teaching, the general associated video of on the classroom, playing magnetic artillery of the teachers that teach, come the student is demonstrated, this mode lacks teachers and students' interaction, and its effect is comparatively general.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and provide " magnetic artillery " to be moved into teaching classroom, thereby increases and student's interaction, submits the magnetic artillery apparatus for demonstrating of quality of instruction to.
For achieving the above object, the technical solution of the utility model is to include solenoid, gun barrel, ferromagnetism big gun nail and the pulse power, wherein said gun barrel is arranged in the solenoid, and described ferromagnetism big gun nail is arranged in the gun barrel, and described solenoid and the setting of pulse power conduction control linkage.By this setting, utilize pulse high current of pulse power moment generation, magnetic field changes around the solenoid, the magnetic field that changes makes ferromagnetism big gun nail that electromagnetic induction phenomenon take place, and produces opposite magnetic field, thereby makes ferromagnetism big gun nail accelerate to the coil middle part under the action of a magnetic field of solenoidal electric current, then by the inertia mouth of pipe that flies out, thereby realized " magnetic artillery " moved into teaching classroom, increased and student's interaction, submitted quality of instruction to.
Further being provided with is that described gun barrel is the transparent tube that transparent material is made, the lower end closed setting of this transparent tube.The whole process that observation of students ferromagnetism big gun nail flies out is convenient in this setting from gun barrel, intuitive is good.
Further be provided with is that described solenoid is that the enameled wire that is spirally wound on the gun barrel constitutes.
Further being provided with is that the described pulse power is formed by being connected in series the power supply, bulb, electric capacity and the diode that constitute pulse power loop successively, and on this pulse power loop gauge tap K1 is set.
Further being provided with is that described power supply is a civil power, and described capacitor is the withstand voltage electrolytic condenser of 1000uF/500V.
Further be provided be described solenoidal two ends with electric capacity mutually and connect, and between solenoid and the electric capacity gauge tap K2 is set.
Further being provided with is also to include the support that is used for fixing gun barrel, and this support is arranged with wheel.
Further being provided with is that described power supply is a civil power, and described capacitor is the withstand voltage electrolytic condenser of 1000uF/500V.Further being provided with is that described gun barrel is long 70mm, and internal diameter is 10mm.Further be provided with is that described ferromagnetism big gun nail is iron nail.
The utility model has the advantages that to have device simple, characteristics such as draw materials conveniently, experimental phenomena is obvious.Demonstrated magnetic artillery to Success in Experiment, allowed student image ground see experiment, perceptual experience is arranged, greatly improved the interest of student's learning physics, and, excited the extracurricular interest of exploring of student by the self-control experimental apparatus.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
