Magnetic Field Relationship between Distance and Induced Voltage Generated by Electromagnetic Pulse (EMP)

Electromagnetic pulse (EMP) damage electrical and electronic circuits by inducing voltages and currents. Electromagnetic Pulse could be generated by any type of electrical disturbance. This can be the result of a microcontroller changing states, to a bolt of lightning, and extremes discharge energy. EMP topology consists of capacitor to store the energy and coil loop to generate the magnetic field. The magnetic field induce the target coil to produce induced voltage. This paper presents the magnetic field relationship between distance and induced voltage generated by EMP. The results show that the distance between the coil loop and the target coil affects the induced voltage on the target coil. The induced voltage at target coil decreases when the distance between the coil is further a part.
