ConclusionConclusionElectromagnetic generator operating should beElectromagnetic generator operating should beconsidered not as a perpetual motion machine, butconsidered not as a perpetual motion machine, but
rather as a system in which flux radiated from arather as a system in which flux radiated from apermanent magnet is converted into electricity, whichpermanent magnet is converted into electricity, whichis used both to power the apparatus and to power anis used both to power the apparatus and to power anexternalload.externalload.
