Obviously I should add: this is idly looking into it with Google. Magnetism is really complicated and I'm no expert. If I've overlooked a complexity it'll probably reduce the effect, although as scanners get more powerful it'll likely increase. Normally you do these kinds of sums and it says "you are nine orders of magnitude away from anything happening" and you can assume the complexities don't matter. This little one-and-a-half orders of magnitude difference is *not much* — I'm confident in saying cornflakes in an MRI scanner aren't a hazard, but I've really no idea whether or how much they'd slide about
