They are an important tool in the repair of older color tv sets, to remove any magnetism from the crt. By the late 60s all but the cheapest sets had built-in automatic degaussing. A magnetized screen will have blotchy color, so that a picture that is supposed to be all white will have some pink in one corner, some green up top, some blue over on the other side, etc.
I discovered that the crt monitor on my work computer has a manual deguassing feature in the on-screen menu. So when I get really bored I will go on and do it, just to see the special effects!
