1. An electromagnetically-actuated clearance control system for a gas turbine engine comprising:
an electromagnetic coil coupled to a first end of a facesheet, the electromagnetic coil generating a magnetic field in response to a connection of a power supply; and
a ferromagnetic sheet coupled to a second end of the facesheet, the ferromagnetic sheet drawn radially-inward toward the electromagnetic coil when the magnetic field is generated, a first end of the ferromagnetic sheet coupled to a first compression spring and a second end of the ferromagnetic sheet coupled to a second compression spring, the first and second compression springs to compress in response to the ferromagnetic sheet being drawn radially-inward.
