I'll do some more reading since the references are extensive ,but that's a very specific and relatively high energy study .
.1-.5 millitesla at the target site .
A cell phone is about , max , .006 millitesla and of course far far higher frequency .
That study is low frequency specific - "
This hypothesis could have an important implication for the possible health effects associated with exposure to extremely low-frequency magnetic fields in the public and occupational environments. "
Magnetic field strength decreases with the inverse square , so , I wouldn't hold a 60 Hz electromagnet up to your head for prolonged amounts of time ,, especially if you are a rat !
An electromagnet or certainly a permanent magnet at a normal distance from the user will be benign .
There isn't any evidence in the world's population of brain injuries or DNA damage from exposure to magnetic fields .
That study is from 2005 .
But , thanks for my new research topic
I'm now interested in how the frequency of the source affects the outcome.
I'll see if this experiment was peer reviewed or expanded upon .
