The description on the website sums it up quite well.
Long story short: extra ionization from the flare causes a current spike in the ionosphere. Magnetometers pick up the magnetic field from that current.
Sorry if it is pedantic, but I think it is interesting that the ionosphere displays the same behavior or response to an EM pulse as the high-voltage inductor in an ignition system. If you are not familiar with ignition system scope patterns I can see this makes little sense to you, which is a shame that could be avoided if this forum provided a means to display images. (one picture being worth ten thousand words)
Yeah, one pulse-type process is similar to another pulse-type process. Not a big revelation.
What follows from that though?
One could also say it's similar in shape to a Christmas tree. And, well, Christmas tree has lights, and during geomagnetic disturbances we observe polar lights. Not one, but two similarities!
Then, polar lights are green, and so is Christmas tree. That makes it three!
Christmas tree is being used when it is cold. But you know where it's cold most of the time? At the polar circles, where the polar lights are! Four similarities.
I think you can see that my analogy is at least 4 times better than yours.
