The DKS tangent field goes as r sin cos…. over a square of (r^2 + cos^2) I woulda thought to see a little strength in the 45 degree region, but WHATEVER, haaaaaaaaaaaaaaaa.

The quantity r^2 – cos^2 IN KERR COORDS is equal to Cartesian R^2 – 1… it works nicely describing a circle in CARTESIAN SPACE… where the radial field vanishes, ahhhh, we mathematicians love this term.

Thus not so bogus after all, when considering the radial field??

Try integrating total energy and tell me it doesn’t come out too low.

It’s neat how this circle at R=1 acts like a barrier to the lines.

>>In Kerr coords, r^2 – cos^2 = 0, so THIS IS THE LOCUS OF ZERO radial field.

Everything looks nice in the far field !!! These fields fail to integrate adequately for energy total. I need to know exactly what yer program figures for color ‘density’ inside…I am sitting down to paper to look at the near-field of DKS squared, energy density. Be right back.

For this plot the program is coloring by the absolute value of the radial field.

For the other plots it’s the magnitude of the field considering both the radial and tangential components.

Oh boy, details, hmmmmm. I HAVE THE NEAR ENERGY DENSITIES. The ‘r’ in the numerator of tangent field kills it, except going out… DENSITY FROM THE RADIAL FIELD goes only as inverse cosine (^4). Thus IT IS SHELVED thruout the center region. AWRIIIIIIGHT.

Putting tangential field into the density figuring, I say it is relatively strong only at “mid-latitudes” near r=1.

The complete field (radial and tangential) was strongest at the equator as shown earlier:

The tangential field, plotted alone below, is stronger just off the X-axis, and maybe this is at mid-latitudes in Kerr space.

WILD… thanks !!! You are right, I am looking at the field IN KERRSPACE.m This is a very interesting lesson mostly in the geometry, knowing how the tangential field goes as sin cos, and is strong at 45 degrees IN KERRSPACE. It must involve also the red line of x-axis, but this is not so clear. I have a problem seeing the red line in the center. Tangential DKS field has ‘r’ in the numerator, and also goes away at the SPIN axis.

Steve I am confused because I thought you said one pic is only radial field. . . Analytically once we are near the x-axis, Kerr ‘theta’ is tied to x as x = sin (theta). Once when I was beating hard around the bush with Alexander Burinskii, I said, how do you write Cartesian radius??? He answered, interestingly, only: r^2 + sin^2 ,,, hmmmmm OK.

Yes, the image at the top of this post is radial only.
