Just looking ahead and wondering how I would check the "magnetism" of a room. I work in an industrial processing plant that has an electrical room where the main and secondary controls are. There are other electrical banks and panels in there along with control charts that I change on a daily basis. I'd like to find out this info in case I end up getting a pm.
Inside the facility there are large pieces of equipment powered by large motors some as big as 120 hp. Would being near any of this interfere with a pm functionality?
Thanks in advance.
