I imagine that a 50,000 ton kaiju putting out a magnetic field to assist its own flight would create a county-sized radar image or something like that.
The problem is since the earths magnetic field is weak as fuck in these terms the Kaiju magnetic field would have to be stupid high. I have no idea how high but you are asking for the powr to not just lift the thing, but propel it forward against aerodynamic resistance that's kinda like a 100mph motorboat hitting the water except worse because supersonic compression is involved.
So I'm pretty sure the magnetic field blanking out radar screens won't be a problem because a magnetic compass would track the monster anywhere it goes. But these kind of megatesla or even higher range magnetic fields would direct affect people in a fatal kind of way, and might remotely induce fusion reactions into vulnerable material as the monster flew past. Also the whole hypersonic shockwave thing remains in play.
Would be pretty awesome if anyone would actually give us that kind of monster doomsday on screen but movies tend not to be that way. Tokyo having a giant crater at the end of Final Wars was pretty utter, but still not what the hypersonic death aura monster would inflict.

Toxic rocket fuel is best rocket fuel, but seconds? I mean if it can lift him, you'd kind of expect it to be more like it 'melt your building' in seconds. The bone will be on FIRE in a lot less then 1 second! More or less instantly. Small Godzilla is supposed to be 50,000 tons and King Ghidorah is much bigger. Even 50kt would require 66 Saturn F1 engines just to lift.
So you imagine every Saturn V first stage launch ever, bundled side by side, all firing together, and that still isn't enough thrust but it's close. If you flew around slowly like this at low altitude you should be constantly destroying and incinerating a several city block wide path as a minimal, and probably igniting a large proportion of buildings over twice that radius.
If King Ghidorah was 150,000 tons we'd need about 197 F1 engines, so a bundle of 14x14 of them plus 1.
High collateral damage just might result from that. Even if you accomplished it without heating a working fluid it'd still be like some constant F6 tornado under the thing.
It continues to seem to me that Kaiju tend to suffer from low strategic damage yields in canon, while in principle of 'existing' they ought to be hyper destructive if they wanted. This suggests kaiju seldom are actually aiming for destruction but more like confused drunken wandering getting into bum fights. A big problem for Japan if attacked constantly, but a lot less so on any wider scale. I continue to collect concepts for Tactically Decisive, Operationally Effective High Strategic Collateral Damage Monster Weapons. Why invent excuses not to use nukes, invent stronger monsters that destroy crap worse!
