AFAIK, the main issue with AM is that it is much more vulnerable to
magnetic disruptions than FM.

Wrong. Take a magnet, any magnet. Wave it around your AM or FM
radio. Hear anything different? You won't. Therefore, forget about
magnetic disturbances.

That's because this magnet isn't vibrating fast enough. If it were to
vibrate at the carrier frequency, you would most likely hear
something.

Also, if there is a solar prominence you can hear the resulting
magnetic disruptions on an AM radio receiver. They sound scary and
enjoyable at the same time.

You can also hear lightning storms. In the US, most of those are in
the south east of the country. Nothing like interference from 3000
miles away. Lightning detectors operate in the 25-50KHz region.
Incidentally, there are about 8 million lightning hits per day, which
is why the noise sounds almost continuous.

The AM audio cause by lightning is so boring. All you get are clicks
and pops. Now a solar prominence, this results in some terrifying
tones on the AM radio, they resemble the second set of tones played by
the Emergency Alert System -- the higher-pitched tones. At times the
cosmically-induced AM radio disruptions sound like the audio you get
when playing the 1st level of the 1st-stage of Super Mario Bros 1 on
channel 4, when the receiver is connected to channel 3. Instead of
hearing the game's music, you here those frightening yet enjoyable
tones. Sometime you can here these same sounds on a PA system or an
airplane. When I was in 1st-grade, the schoolbus I went in had a CB
radio which would often make these scary sounds. Such sounds would --
and still to a much smaller extent -- make my eyes water in fear,
dissociation, enjoyment, and psychdelia.

When the sun emits a prominence, that prominence causes high-power
waves of magnetic energy in the RF region to be emitted. These waves
can be heard on the AM radio on Earth. This is the sound that affects
CBs and other radio receivers using AM.

The main reason why anyone would prefer FM over AM is if they can't
handle these terrifying sounds w/out going hysterical.

There are some who have had emotionally-strong experiences with these
sounds -- perhaps a fire on an aircraft -- when these sounds are
heard, flashbacks occur which can entirely consume an individual's
psyche. Such an individual might not even know why he/she is getting
psychologically-excited while listening to the sounds because the
brain involuntarily suppresses emotionally-intense memories.

Here is what use to happen -- and still happens to some extent -- to
me when I hear the sounds I describe:

1. Psychogenic shock and psychological dissociation due to the extreme
fear/enjoyment caused by the sounds.
2. Flashbacks of my house in Stamford, Connecticut in which my parents
and me moved out when I was around 2.5 years of age.
3. Enjoyable yet terrifying thoughts about outer space due to the
knowledge/belief that the source of the sounds is in outer space
4. Fear of -- and obsession with -- magnetism due to knowledge/belief
that the radio waves are magnetic
5. Decrease in heart rate
6. Slow deep breathing
7. Muscle relaxation
8. Increased tear production

Ain't it interesting when things that are so scary are also so
enjoyable at the same time. Why else would they develop virtual
reality systems? Or visit outer space?

We tend to enjoy what we fear. At times.
