At least those old news reels had traces of the audible static of old magnetic sound recording to remind you that the pictures in front of you were actually moving.
The radiation belt, which contains "two concentric rings of charged particles trapped by Earth's magnetic fields" doesn't affect current astronauts going to and from space because they are moving too fast to be hit by the radiation.
At very high doses, exposure to a magnetic field can cause the muscles to twitch and some people have reported feeling dizzy or sick when moving their heads quickly around a high-field magnet.
