The study found no observable effects from 48-hour exposure to a 20,000 gauss magnetic field in two rhesus monkeys.

Plain English Summary

Summary written for general audiences

Evoked potentials measured inside and outside the magnet were essentially the same, and the latency of fast and slow waves from limb to brain was not changed by the magnetic field. Heart rate was lower inside the magnet, while blood pressure results showed opposite directions in the two monkeys. Noticeable changes in blood hematology and chemistry can be attributed to the trauma caused by the implantation of the cortical electrodes. From the tests which were performed, as described above, we conclude that there were no observable effects in the two monkeys.
