Thank you john, and yes carol it is amazing that we depend on something as common as magnetism and the Article you linked is a great read thank you. John I was reading a book and it used the theory that a machine capable to create large magnetic fields to shrink people.
I’m glad you like my answer. I’m not sure what kind of machine could shrink people?! It’s just as well large magnetic fields don’t shrink people as they’re used in MRI (Magnetic Resonance Imaging) machines to get pictures of the inside of the body!
