Assume you mean the flux density at saturation?

The core will only run at around 377 gauss so probably not an issue.

It's the
coercivity that will eat you alive here, though. But if you can measure,
you can do all on your samples.

Yes. The core will run at about 1.8 Oe at 2MHz which looks high on the
type 43 data sheet.

Measuring the hysteresis will be fun. This looks feasible...
