Some additional analysis of data from the Event Horizon Telescope images of the M87 supermassive black hole revealed information about the magnetic fields in the accretion disk.

How do these magnetic fields propel the matter jets produced by active galactic nuclei?

I would imagine that the strength of the magnetic field intensifies around the horizon in the same way that the gravitational field does. Since the electromagnetic field is orders of magnitude stronger than the gravitational field it should be no surprise that this effect is present. They are both inverse square in nature.

They discuss the jets created by them. I've read to through about half way. It's interesting.

They discuss the jets created by (neutron stars)

Did you provide the intended link?
 This article was about the interior of neutron stars, not about generation of jets?
