[Phys-l] Winding a transformer (was induced electric field)

[Brian Whatcott <betwys1@sbcglobal.net>]

I wonder if it would be helpful to notice that if one winds a one turn 
secondary coil on an energized transformer primary and its core, the 
output voltage across the ends of this one turn are sensibly similar no 
matter if the secondary turn's diameter is twice or four times the 
magnetic core's cross sectional width?
