Embodiments of the invention can provide systems, methods, and an apparatus for providing a magnetic seal. According to one embodiment, a system having a magnetic seal can be provided. The system can include a rotary machine having a first component and a second component. A magnetic seal can be mounted to the first component and positioned relative to the second component to provide a gap between the magnetic seal and the second component. The magnetic seal can include a first magnetic element and a compliant material adapted to adjust in response to a force exerted on the magnetic seal by a second magnetic element. The second magnetic element can be mounted to the second component so that the gap between the magnetic seal and the second component can be modified in response to the force exerted by second magnetic element on the magnetic seal.
