> Interesting that he didn't feel gradual increase of pull force while he was approaching the MRI machine. There isn't a gradual increase in pull when magnets are involved. My wife used to work for a company whose product involved powerful magnets. For a while they produced a demo kit in which a magnet would hold a large ball-bearing levitated against gravity. That thing was lethal. If the ball-bearing approached the magnet too closely it instantly became a dangerously fast finger-crushing hammer.
