A propulsion system for a craft having an outer skin comprises an array of electromagnets 14a-c disposed in operable proximity to the skin, an activation and control sub-system for activating the electromagnets and controlling the activation sequence of electromagnets, and a dynamic magnetically responsive material 12b responsive to dynamic field patterns, in operable proximity to the array of electromagnets and to a fluid or surface H in or upon which the craft is disposed. The craft is propelled by activating and deactivating the electromagnets sequentially. The magnetically responsive material may be a magnetic pseudo fluid, particles or cilia like appendages. A protection system for a craft having an outer hull H1 and an inner hull H2 comprises an array of electromagnets 14 between the hulls and a dynamic magnetic pseudo fluid (MPF) 10, where the MPF can be projected outwards towards a threat, e.g. missile 10, by activating one or more electromagnets. |
