The article doesn't even mention frequency. Maybe it's just a static field.

All in all, the article leaves way to many technical questions unanswered, making it very hard to figure out whether or not there can be health impact. That being said, an MRI scanner also uses strong magnetic fields and there are tons of safety measures for that, but the fields are (as far as I can imagine) an order of magnitude stronger than what is used here.
