Magnetic fields within a toroid inductor.

[tinman]

So what dose the magnetic field look like within a toroid coil?. Is the magnetic field contained within the toroid core?,and wich field is it-north or south?.
My first test looking at a field being expelled outward from the toroid coil.But listen carefuly to the video near the end.

You can find it in Wickipedia and in many good books and articles about transformers:

This PDF explains it quite clearly as to how the fields propagate through a toroid core and coils. I believe it is correct.  Its only 18 pages.  Read carefully, and you will get the picture.

Sorry. Hit quote instead of modify to correct spelling of 'cor' to core.    Too bad there wasnt a delete feature that had like a 1 min time frame in which to do so if a mistake were made such as I just did.
