The shape of the toroid is just a field control convenience and the hole
is
absolutely irrelevent to anything electrical. The plate or "web" just
allows a convenient mounting method.
The plate adds zero isotropic capacitance to the system unless the sumed
cross sections are microscopic or represent less than a total of 50% of
the
diameter.
