[TCML] hoop stress in primary coil

[Bert Hickman]

Hi Jim,

A very straightforward analysis of B field and resulting hoop stress 
calculation for a simple loop can be found in section 3.3.1 of the 
following article from MIT.

http://ocw.mit.edu/NR/rdonlyres/E23FEEB3-AAEC-434E-997B-6950DAD6A121/0/chap3.pdf

The magnetic pressure (P) is proportional to the square of the B field, 
and the resulting hoop stress for a "thin" turn is P*(a/t), where a = 
radius of coil, and t = thickness of the turn.
