Retrieved from Wikipedia CC BY-SA 3.0 Toroidal devices are relatively successful because the magnetic properties seen by the particles are averaged as they travel around the torus. Retrieved from Wikipedia CC BY-SA 3.0 Most bulk mechanical, optical, thermal, electrical and magnetic properties are significantly affected by the observed microstructure. Retrieved from Wikipedia CC BY-SA 3.0 Companies were being advised to protect sensitive electronic information from the effects of a nuclear detonation's electronic magnetic pulse. Times, Sunday Times The study involved 16 healthy participants, aged 21 to 40, who were each given a detailed brain scan to locate a target for the magnetic pulse. Times, Sunday Times The idea appears to have been to create compact toroids of high-density plasma that would be ejected from the device using a massive magnetic pulse. Retrieved from Wikipedia CC BY-SA 3.0 One day they get hit by a raya unique magnetic pulse that changes everything.
