What is the mechanism by which a field spreads.  As the magnetic field 
rushes away from a magnet, what exactly is causing it to move at all.  Why 
does a strong magnetic field tend to spread.

I have searched through 650 questions returned under "field" and a few 
more specific querries.  Sorry to resubmit.
