When you think about it a magnet's magnetic field can penetrate just about anything. Two magnets can hold themselves up against metal, lead, plastic, and so on. If we were to put the magnetic field in the electromagnetic spectrum it would up higher than gamma rays and cosmic rays because it can penetrate so much more than they could. What is interesting is that the magnetic field has a high wave length but unlike the gamma and cosmic rays the magnetic rays have no harmful effect onto a human that I know of. I just thought it was a interesting concept to think of a magnetic field being measured against other electromagnetic radiation. The whole magnetic spectrum is so interesting, like how radio waves can penetrate a wall but light can't. Or how comic rays make carbon-14. Just like how theirs small waves like gamma rays, their gonna be high waves that far exceed the size of a football field or even rays that are bigger than our universe. Fascinating stuff
