Some magnetic news

Magnetic storm detected in Hanoi.

According to Saigon Times, last Thursday Institute of Global Physics in
Hanoi recodred a magnetic storm.  The Earth's magnetic field, usually
staying at 0.44 Gauss (G) in Hanoi, was reduced to 0.9 mG during the
storm. 

Magnetic storms are caused by sharp increase of solar activity and may
interfere with radio comminication. 


Magnetic acupuncture

The University of Washington released Apr 10 a study of multiple
sclerosis treatment with pulsed 4-13 Hz magnetic fields at 50-100 mG. A
device the size of a watch was attached to an acupuncture point and tuned
to frequencies the patient was deficient in. So how does it work? "The
brain is an organ that emits electrical energy," explained Dr. Todd
Richards of the Radiology Department. "This magnetic device acts like a
vitamin supplement by giving back to patients those frequencies they are
deficient in." No comment!
