Abstract
Various embodiments may include a drone for triggering sea mines by means of an external magnetic field. For example a drone may include: a drive having an electric motor; the electric motor comprising a stator and a rotor mounted on a shaft. The stator includes a stator winding arranged on a first carrier. The rotor includes a second carrier and a magnetic or electromagnetic element arranged on the second carrier. The element may be configured to magnetically interact with the stator winding to form a superordinate magnetic field during operation of the electric motor. During operation, the electric motor forms an external magnetic field outside of the electric motor with a magnetic flux density of at least 0.5 mT.
