thanks for the info,

that dude should have provided the numbers to back himself up, back of 
the envelope should do.


so how much is the field 655,000 miles away from a one T source ?

how much fuel on board with the sattilite need to compensate for pushing 
particals around?

Gamma rays are not deflected and come in at full strength to the ground, 
on earth the atmosphere protects us from 95% of them. so how much gamma 
can a crew take ? a year or two ?

and again, to cosmic rays, at what angle can they be deflected  from 
orgional their path, using a magnetic field, is it only 1 or 2 degrees ?
