Re: Magnetic Feild of Primary

Hi cory,
The flux would look like a big doughnut that was smooshed into a point
down the center of the vertical axis of the secondary spacing. From the
outside looking at it, it would look like a ball, but if you could see
the flux lines of charge density you would see the doughnut shape.
I've often wondered if there was any "dead zone" down the center, but i
doubt it now?
In the real world though, I bet the shape of the doughnut is all twisted
and distorted by objects in and around this field. some concentrating
and directing some of the lines with there metal surfaces, and this
distorting the fields opposite. Remember that the doughnut goes under
the primary too, so it would look really cool to see the actual fields.
Maybe some massive data aquasistion units with magnet field sensors will
someday be used to get these measurements and we could get a 3d pic of a
field, neat!
