Whoa there, this isn't the kind of magnet you find on your fridge door. TMS uses pulses (not static fields) from a 2 tesla magnet. For comparison, the Earth's magnetic field is 31 µT and a fridge magnet is 5 mT.
But, the fact that it's a pulse is the more important than the field strength: the goal is to produce a current in the brain via Faraday's law. In order to do that, you need a magnetic flux, and therefore a rapid change in the field strength. Sitting in a magnetic field, no matter how strong, is not going to induce a current.
tl;dr: Any theories about the Earth's magnetic field affecting moral judgement are bull. Ditto for everyday magnets.
(Correction: I just read the paper. They used a 3T field in this study, not 2T.)

- nitrogen 17y agoThere are other species that are influenced by or rely upon the earth's magnetic field. I'm not a biologist and haven't heard of any evidence that humans are magnetically sensitive in some way, but knowing that the trait has evolved in multiple species suggests it could be found in some form in some humans.
