creates a magnetic field in the steel ( basically making it a temporary
magnet), the thicker the steel, the longer the magnetic field wants to
stay. Thus the advent of laminated cores, it still allows a field to be
produced to transfer energy to the other windings, but also allows the
magnetic field to dissapate faster and be a bit more efficient when the
current reverses the direction ( A/C application). Most standard
transformer cores operate in the 50 -60 Hz range, if you try using a
"standard" core in lets say a 400 Hz enviroment, the transformer core
will heat up and loose its ability to transfer the energy properly to
the secondary windings... things like inductive heating, saturation of
the core and several other anomolies occur.

I know I'm probably getting into some basic physics here, but could
someone
explain the purpose of multiple laminations in transformers and inductive
ballasts, vs. a solid core of iron/steel? Is a solid core good for any
type of
ballast? Thanks,
Neal.
