An electrospray device for generating electrospray from a ferrofluid. The electrospray device includes an emitter, an extraction electrode, and a magnet. The emitter is configured to receive a ferrofluidic liquid. The extraction electrode includes an aperture and is positioned a first distance from the emitter. The magnet generates a magnetic field in a first direction toward the emitter. The magnetic field causes Rosensweig instability in the ferrofluidic liquid, and generates a ferrofluidic peak in the ferrofluidic liquid. The magnet is positioned a second distance from the emitter, and the emitter is positioned between the extraction electrode and the magnet. The ferrofluidic liquid is biased at a first electrical potential and the extraction electrode is biased at a second electrical potential. A difference between the first electrical potential and the second electrical potential is sufficient to generate an electric field at the ferrofluidic peak that generates electrospray from the ferrofluidic peak.
