Description of drawings
Fig. 1, be the utility model magnetic artillery synoptic diagram;
Fig. 2, be circuit diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: as depicted in figs. 1 and 2, magnetic artillery is made of gun tube 1, electric capacity 2 and direct supply; Gun tube 1 is a solid bar, diameter 30mm, long 250mm, gun muzzle has recess, is used for placing small magnet, outer winding around 300 circles of body, the two ends of coil connect the both positive and negative polarity of electric capacity 2 respectively, between discharge switch button 3 is set; Electric capacity (10000MFD 63VDC) connects direct supply, between polyphone charge switch button 4 and current-limiting resistance 5 be set.Present embodiment makes the gun carriage model with magnetic artillery, and gun muzzle of gun tube 1 is upward to be placed on the car body, and discharge switch button 3 and charge switch button 4 are arranged side by side the rear portion in the compartment, and remaining part is arranged at interior.
During demonstration, place small magnet (magnetic flux 3000 Gausses) in the recess of gun tube 1, the magnetic pole magnetic of the recess of the gun tube 1 that produces behind magnetic and the coil electricity is identical.Press 4 pairs of electric capacity chargings of charge switch button earlier, after charging is finished, disconnect charging circuit; Press discharge switch button 3, coil electricity produces magnetic field, according to principle of same-sex repulsion, and the small magnet gun muzzle of being ostracised out, directive is at a distance.
The application of technical solutions of the utility model is not limited to the gun carriage form of the foregoing description, also can make styles such as tank, panzer or artillery.The utility model is not limited to as teaching aid, also can be used as the toy for children production and sales.
