The invention discloses an electromagnetic emission presentation device, comprising a gun barrel, a battery, a discharge circuit, and a charge circuit. The gun barrel is provided with tubular structures of an entrance port and an exit port of a shell; the battery is internally hollow and used for placing metal shell, wherein the entrance port of the shell is connected with the inner part of the battery, and the gun barrel is moveably installed on the battery, and the gun barrel can realize the adjustment at many angles on the battery; the discharge circuit has a coil and a first capacitor, both ends of the coil are connected to positive and negative electrode plates of the first capacitor, and the coil is wound on the gun barrel; the charge circuit is provided with a bridge pile, and two input end of the bridge pile are connected with power source, and two output ends of the bridge pile are connected to the positive and negative electrode plates of the first capacitor, wherein a shell filling opening is arranged on the battery and used for placing the shell in the inner part of the battery. By using the electromagnetic effect principle, the device generates big magnetism, thus the shell can be shot by dynamic energy, the device is ingenious in structure, simple in operation; the device adds the interestingness, improves the study effect, repeatedly displays operation, and improves the display effect.
