That would be a time-varying magnetic field, which I told you about. However, a generator has something you don't - a good close coupling.
Time-varying mag fields fall off in power density as the sixth power of the distance. Thus, even if you had a close coupling, and you won't, you
can't get any distance out of your magnetic drone damager.
So if you have a circuit that's designed to handle 120 volts, and all of a sudden a magnetic field, stronger than that of the 120 volt source comes
along, then you're going to induce a larger current than the circuit is designed to handle. Electricity is created by magnetic fields. The stronger
the field, the higher the current.
Magnetic fields don't come in volts. Current can be induced by a time-varying magnetic field, but only to the extent that it's closely coupled into
your circuit, which you won't get. It works better with long conductors, which I also said and you missed, but you won't have those with
microdrones. Bad coupling + distance + short conductors = piddly barely detectable currents. Not volts.
