An electrical energy generating apparatus includes a hollow pipe, permanent magnetic fluid held in the hollow pipe, a ferrite film wrapped around the hollow pipe, a heat source receiving device joined to a portion of the hollow pipe, and an induction coil wound around the hollow pipe; the induction coil being connected to a storage battery; in use, the heat source receiving device will receive heat energy from heat sources so that a portion of the fluid is heated, and temperature and pressure difference comes into existence in the fluid, and convection in the liquid happens to circulate the nano-chip permanent magnets around the hollow pipe; therefore, there is change in a magnetic field between the nano-chip permanent magnets and the ferrite film, and in turn the induction coil produces electric field, and electrical energy is produced, and next stored in the storage battery.
