Hi ,
Do you agree that the Mag Inc Kool mu torroid 0076076A7 has a B value of 0.455 when it has 15.4A of current flowing in it?
....This is for 2 stacked 0076076A7 torroids, with 42 turns around the 'couplet'.
Working as attached.

Mag Inc Kool mu torroid 0076076A7 datasheet

The calculation has been done using the "bit by bit" method...... that is, increment H by even , small steps, calculate dH as you go, then dB = uo.ur.dH........then accumulate all the little dB values and read off what you have for B(total) at 15.4A.

(BTW, ur is recalculated at every H value...from the reluctance)

To get the answer directly, you'll review the DC magnetization curve in Magnetec databook. I read a B value of about 0.47 T.
