This issue is not new. I’ve not read the article, but I’m willing to bet that it does not address the fundamental problem, being that magnets are cheap and do provide useful albeit subjective information. Of course education and motivation are key but until someone comes up with a better alternative, magnets will never go away. There is a small portable meter that tests for magnetic susceptibility built as a proof of concept (shown to me by Jerome Gattacceca), but it is presently very expensive. If its selling price can be brought down to ~$50 through volume manufacturing, then we as a community will start making inroads, but will still take a while and require significant effort to train and educate.
