چکیده
When a momentary large current in opposite directions flows through the two opposing spiral coils, strong magnetic field is generated coils. The creates an impact force between permanent magnet placed under of actuator enhanced because Lorentz by static field. In this paper, we introduce principle electromagnetic generation and calculation method force. fields coil are analyzed finite element method. Then derived from waveform shape examined to maximize electromagnet
