SUMMARY

Coiled magnetic fields are fundamental in the formation of jets observed along the rotational axes of black holes. These magnetic fields originate from the matter in the accretion disk surrounding the black hole, rather than from the black hole itself. The properties of the matter in the accretion disk, including its dynamics and charge, play a crucial role in generating these magnetic fields and the subsequent jets. Current understanding indicates that while the exact mechanisms remain under investigation, the relationship between magnetic fields and jet formation is well established.

I have read that coiled up magnetic fields are responsible for the jets that are observed along the axis of rotation of black holes.

I'm having trouble visualizing the "coiled up" magnetic field and where it comes from?

I presume that the field does not come from the matter in the black hole itself, right?

If it comes from the matter in the accretion disk, what are the properties and dynamics of the matter creating the field?

What are the properties of the matter being spewed in the jets in either direction? Any particular charge?

I get it: we don't know yet.
