Another example: Wireless phone chargers. Now, the fact that wireless chargers emit RF energy is hardly surprising -- that's how they work -- but I was still surprised when I found that my new charger completely obliterates the AM radio band within a 3' radius.

It's probably caused by induction in the radio's circuits, not by charger emitting radio waves.

  Perhaps, but wouldn't that affect FM reception too? I only get interference when tuned to the AM band.

    FM capture, perhaps? FM reception is naturally much more resilient to interference so long as the absolute magnitude of the interfering signal is lower.
