I'm not sure what it is demagnetizing either. Some of the static charge will cause a magnetic field, and maybe some of that is reduced.
Getting back to what would be my concern is the damage one of those TV units can do. Make sure you use it several feet, maybe at least six foot, or more to be safer, to reduce the risk of causing any damage to your electronic gear, plus something else in the area. Especially your turntable. Some watches may still be at risk too.
I had a large one in the 60's, and it was potent. I imagine the smaller ones still have a potent field around them also. Some do it yourself people did cause problems to a lot of things back in those days, using one of these.
