Yeah it’s difficult or impossible to have an intuitive sense of this. This might help though:

Electricity and magnetism are fundamentally linked to each other. They are not exactly the same but they work in similar ways.

A radio antenna works by accelerating the electrons in the metal back and forth. You could theoretically make a radio signal by doing the same with a magnet, but it would be much, much harder since you would have to move the whole mass of the magnet back and forth, not just some of the electrons.
