Depending on air pressure and humidity, air ionizes around 1kV-10kV/cm. The lightning strike travels inside the ionized air channel.
What stuns you when lightning strikes nearby, is the voltage difference between your two feet as the potential dissipates over distance, your two feet
experience a difference in potential thus electron begin to flow through you.
When lightning hit's you directly, you just were more conducting than the break through ionizing voltage needed for your height. So if you are 180cm
high, that's at least 180kV. And the voltage is not even the problem, as soon as the streamers connect, it's essentially a short cut, cutting down the
voltage to almost 0V but because P = U*I the energy needs to stay the same, so millions of ampere flow.
That's the moment you see the lightning strike disconnect, it was because the air could not be kept ionized after the potential drop, it breaks up,
but there is enough molecules left to help lowering ionizing voltage so it can reconnect.
If that happens fast and a couple of times, the EM field saturation around the lightning strike will fluctuate and we all know: Fluctuating magnetic
fields is what does the work.
However, lightning strikes emit roentgen flashes and other EM too. That might as well have an effect on them.
