Back to magnetic basics

I was picking through my pile of books which I want to get to sooner-than-later and read through a bit of Field and Wave Electromagnetics. I decided I shunned magnetics and inductors too much when I was in school and decided I needed to suck it up and become better versed. The last time I worked with any type of inductor was my home brew 6 meter 4-400 amplifier.

Shown in the image is just a LM555 configured as one shot attached to an IRF530 which I originally had a driver but realized it was pointless as I could run the 555 at 12V and it would work just fine. This configuration was 5A which is too much for my breadboard but not a big deal at 10ms.
