Specify Magnetics

DESIGN PHASE:       preliminary design
SUB ELEMENT NAME:   specify magnetics
VARIABLE NAME:      [HECMAG]
DATE:               REVISION LETTER:    REVISION DATE:  
APPLICABILITY:      [MAGNETIC COUNT] > 0

ACTIVITY:  Determine detailed requirements and specify magnetics
for design by magnetics designer or outside vendor.

OUTPUT:  Report specifying magnetic design requirements.  Consists of
detailed requirements and general requirements invoked by
contract (Mil Specs, Class, Grade, materials, processes, etc), or
detailed requirements and reference to documentation containing
general requirements.

ALGORITHM:

[HECMAG] =               engineering hours to specify magnetics
0*                       hours per magnetic device
[MAGNETIC COUNT]+        number of magnetic components in circuit
0*                       hours per terminal
[MAG TERMINAL COUNT]     total number of terminals on all magnetics
