The high temps in the spark channel, usually over 5000-7000 degrees
F. will quickly allow the magnets to de-polarize and loose their magnetism.
You can quickly remove the magnetism from a magnet by heating it.
Not work the hassle, and as Gary indicated, no gain.

While you'll find the topic quite often in the archives, I can't recall
a single instance of someone actually having built a magnetically
quenched gap, AND having demonstrated that the presence of the magnets
offered any benefit. Usually such threads dwelled only on where to buy
very strong magnets.
