A magnifier works very similarily to a regular two coil Tesla coil.
If you build a magnifier, you're unlikely to see any advantage in
terms of spark length compared to a two coil Tesla coil.  The
magnifier may have a theoretical advantage as shown by
Antonio's work (it's a matter of having all the energy in the
resonator at one time).  To achieve this advantage requires;
1) Much tighter than normal coupling, 2) Faster quenching than
can be easily achieved with mechanical quenching, 3) Keeping
the operating modes steady despite spark loading.  If the three
factors above are not achieved, then the output will be about the
same as a two coil system.  Although
the driver section of a magnifier uses tight coupling of perhaps
0.4 or so, the overall system coupling (see Antonio's formula),
tends to be much lower, similar to the coupling of typical
two coil systems.  When all is said and done, most folks
chose to build the classic two coil design because the
magnifier fails to show the hoped for benefits, despite its
extra complexities.  A possible advantage of the magnifier
is a purely practical one.  The separate resonator section
may make the setting up of a large coil easier, in the case where
a coil needs to be wheeled out of a garage or storage shed
before operation.
