AB: Entering the atmosphere meteoroids ablate their atoms and form columns of ionized particles. These columns or meteor trails act as pulses of electric current generating electromagnetic signals which can be observed on the ground. The objective of this paper is to develop a model of electromagnetic pulse caused by a meteor trail. The amplitude of such pulses is determined by the mass and velocity of the particle entering the ionosphere along with the ionospheric parameters such as the ambient electric field, plasma density, etc. Detected by a ground based magnetometers, those pulses can be used for the ionospheric and meteor diagnostics.
