Electromagnetic emission device and electromagnetic emitter

The invention relates to an electromagnetic transmitting device and an electromagnetic transmitter, the electromagnetic transmitting device comprises a plurality of sections of transmitting channels, an armature and a pulse source, the transmitting channels are connected in parallel to the pulse source, the transmitting channels are located on the same straight line, the pulse source is used for providing current for the transmitting channels, and the armature starts from the first section of transmitting channel; and the target body moves under the action of a magnetic field generated by the current, slides out of a certain section of launching channel and then enters the next section of launching channel until the target body is pushed to slide out of the tail-end launching channel. By adopting the device, the speed of marking the launching channel by the target body can be improved. 本申请涉及一种电磁发射装置和电磁发射器，该电磁发射装置包括多段发射通道、电枢和脉冲源，各发射通道并联接入脉冲源，各发射通道处于同一条直线上，脉冲源用于为各发射通道提供电流，电枢从第一段发射通道开始，在电流产生的磁场作用下运动，从某段发射通道滑出后，进
