Looks quite good, actually. Like Fred says, integrate, then you will
have it right.

Try amorphous or nanocrystalline cores, too. They switch quite quickly.
I've built a toy circuit that generated enough harmonics to cause itself
to ring a bit; the risetime was under 1us.

Physics guys use the stuff to generate fast (1us) current pulses for
particle accelerators and junk. They drive them with 3kA+ IGBTs, which
don't even switch as fast (~1us). Lots of power density.

Where can i buy some?
Are there various sizes available?
