Below is a amateurish video which is amenable to obvious improvement;
with an eye towards being a candidate for Bill B's infamous:
UNWISE MICROWAVE EXPERIMENTS page

... and might indeed be a candidate for the kind of experiment which
combines chemistry with electromagnetism - in hopes of finding an energy
anomaly which would otherwise be impossible with 'only' electromagnetism
or 'only' chemistry, and/or 'only' wet cell electrolysis.
This is only a basic start, and a "real" experiment would try to
ascertain some kind of P-in to P-out ratio. For that one would need a
"sacrificial" oven which will be drilled with a thru-hole so that
hydrogen produced can be vented out and recombined in an external
calorimeter.
This experiment does not 'yet' employ a permanent magnet or array, but
that is a possible addition which might help, by providing additional
cross-field polarity - in the splitting of water. This experiment does
not yet employ catalysis or even electrolytes. It is very basic.

CAVEAT: #1 as Bill warns: this can be UNWISE for the inexperienced
CAVEAT: #2 for the following reason, this one is at least twice as
unwise as normal.
REQUIRES A minimum 1200 Watt Microwave Oven ! with an internal
microwave energy level of around 1 kW for threshold results.
Most household microwave ovens produces too little net microwave energy.
Don't waste your time with an 800 watt oven - which would normally only
give 500-600 watts of net microwave energy. This experiment requires
almost twice that much as a threshold for ~ half-liter of steam.

Procedure
Step #1, Secure a paper towel, shot glass, and a mason jar, or equivalent.
Step #2, Fill the shot glass quarter full of water, place it inside the
microwave oven on top of the paper towel, and place the mason jar over it.
Step #3, Turn on the microwave and bring the water to a boil to force
atmospheric air out of the mason jar. Hot vapor and steam will push most
of the air out. The idea is to start with mostly water vapor.
Step #4, Quickly open the oven and place a spark gap (to ignite the H2
and O2 which is formed) inside the jar. It can be a 12 cm long piece
magnet wire made into a circular shape with a gap no greater than 1mm,
placed inside the mason jar, but keep it out of the shot glass and away
from the paper towel. You don't want to dally around and let air replace
steam. If you do this in step 3, the paper towel might ignite. It gets
too wet to ignite this way.
Step #5, Turn the microwave on for 3 to 5 seconds, and you be Burning
Water. Hopefully the mason jar will not burst.
Step #6, repeat steps #1 through #5, but use a classroom Spectrometer,
and watch the hydrogen line.
Electrolysis requires more than a 1.2 volts gradient, and technically
this will never happen with microwaves. That in itself is somewhat hard
to explain, and I will restrain from mentioning the H word (below ground
state hydrogen)... and yes, this seems to require around 1 kW of
microwave energy as a threshold in order to make a half liter of steam
unstable enough to split - in a few seconds of irradiation. At this
stage you are far below unity but not as far as you might imagine.
Step #6, Ascertain roughly how much hydrogen per second is being
produced by removing the spark gap and venting the hydrogen through a
bubbler and then a separation membrane, like GoreTex.
Step #7, Apply enhancements, one at a time and look for increased H2
generation.
Step #8, If (huge IF) there is any anomaly in H2 output with some
enhancement - then move on to BillB's infamous microwave lawnmower
experiment ;-)
