How does a transformer make clicking sounds when being powered ON or when it is bucking/boosting voltages, without having any moving parts inside?

Iirc and GCSE physics doesn’t fail me, one possible reason could be magnets clicking together. To make a transformer requires wrapping copper wire around a ring many many times, but robots can’t/couldn’t thread wire like that to wrap it quickly, so instead of an O they wrap the wire around a U or two C’s and put them together to make an O. This means however there’s a very small gap between parts of the metal the wire is wrapped around, and as the metal core gets magnetised many thousands of times a second, the two cores repeatedly get attracted to each other, clanging together and making the slight humming sound. Further to this if the gap increases the sound might get louder or the frequency change.
The following video clip from a documentary film about transformers shows some of the hidden moving parts that they have as internal components:
