Primary magnetic field plots
Original poster: Vardan <vardan01@xxxxxxxxxxxxxxxxxxxxxxx>
For my little SISG coil, I got the Ansoft Maxwell 2D thing going:
Here are the flux lines of the coil set up with the MOT under the
coil and a fan to the right side:
Very few flux lines make it up to the top terminal and the aluminum
fan seems to be transparent to magnetic flux. The big iron
transformer bends the lines around.
We then can look at the B field (in Teslas ;-))
The transformer attracts some of this field and is energized by it slightly.
The plot of field energy is where the "power" is at:
The power stays "very close" to the primary coil turns. That is why
those big metal things in the area of the primary do not affect
things much. If we increase the sensitivity, we can see more detail:
The energy still clings very close to the primary but you can see it
touching the secondary now. If we really turn up the magnification,
you can see the transformer having a tiny effect:
Sort of cool!!
