Why does holding a strong magnet up to your brain not do anything bad?

I understand that the brain does not operate completely off chemistry and uses electricity, especially within the neurons, so it seems that there would be a fair assumption that holding a good powerful magnet up to your head would have some deleterious effects and at least be "felt" in some way (distorted thought patterns or seizures). Is there a biochemical reason why you can scramble tapes and screw up a lot of circuit boards by goofing with a magnet, but the brain is impervious?
I'm aware that magnets are a staple of alternative medicine, but since this is mostly voodoo (or empirical at best) it's not really the answer I'm looking for.
