Magnetic forces are omnipresent and are the key to progressing our collective technology. They can assist in transportation, safety, computer, medicine and space exploration (among other things). Everybody who has a elementary school education is aware of magnetic waves/forces. The next step in understanding how to harness their potential is to combine the idea of polarity with harmonics (speeds). Magnetic waves move at particular speeds depending on the type of matter, so the general idea is to focus on what speeds are correlated to different elements/matter (for example, metal, soft tissue, light, Earth's nickel-iron core). This is not an easy undertaking, of course. It will take hundreds/thousands of attempts through trial and error. It is not the task of an individual or small group.
The two primary functions for magnetics in transportation is to propel vehicles faster, as well as protect them from (all) collisions. The first objective would involve a magnetic 'engine' which would spin magnets at the speed correlated to the Earth's inner core (composed of nickel-iron). The trick is to create a polarity that would repel from the Earth's interior, causing the phenomenon of 'anti-gravity'. This could begin with mag-lev roads/freeways but should evolve into airborne vehicles.
In regards to safety, each vehicle should be equipped with magetic strips that could repel other vehicles or other particular metal objects. It would not, for example, stop somebody from slamming into a tree or driving into a body of water. It would, however, stop vehicles from touching each other, instead it would create a 'close call' situation where the magnetic forces would repel the vehicles away from each other instead of colliding.
Magnetics could be utilized to protect individuals from such things as gunfire, grenade shrapnel and many other metal based weapons by creating a small magnetosphere around the person. This could accomplished through a belt (or other personal accesory such as a watch).
