There are also techniques for the TEM (transmission electron microscope) to visualize and measure magnetic fields such as electron holography.
Esentially by splitting the electron beam in two, passing half through vacuum and half through a magnetic sample, then recombining the beams, you can extract magnetic information from the interference pattern of the two beams with some Fourier analysis magic.

I have a writeup with examples from a project i did years ago on my blog, if anyone is interested: https://longcreek.me/blog/2021/holography-intro
