Extra coil can be more or less beside the secondary but should to be far enough
away so the sparks do not reach the secondary. However the rod that
connects top of secondary to bottom of extra coil might then have a
rather steep slope. To reduce this slope, the extra coil can be raised
some relative to the secondary. Also moving the extra coil even
farther away reduces the slope of the rod. If rod has too much
slope then the sparks might hit the rod. There's no need for
the extra coil to be fully above the secondary though. If you
google Tesla Magnifier, some images should come up.
Yes the power companies use corona rings too. A corona
ring is basically a very skinny toroid.

Does the extra coil have to be physically above the secondary or can they be beside each other? I will google corona ring. Is that like what the power line companies use?

In a magnifier, the secondary generally has much lower
inductance and thicker wire than the extra coil (3rd coil).
The primary and secondary are very closely coupled at
k = 0.35 or higher. Usually a long metal rod or tube
connects the top of the secondary to the bottom of
the extra coil. The secondary has a toroid or corona
ring at the top and the rod connects to this.

Thanks will try that when I'm off again. Since you brought up magnifiers am I right in that the top of the secondary toroid has gto wire that will feed another secondary coil just like the first?
