1. An electromagnetically-actuated clearance control system, comprising:
a first electromagnet in a fan case;
a kinetic plate coupled to a second electromagnet arranged in a magnetically repelled position relative to the first electromagnet;
a controller to generate a signal that causes the kinetic plate to move radially in response to a measured clearance between the kinetic plate and a blade tip;
a third electromagnet in the fan case; and
a fourth electromagnet coupled to the kinetic plate, the fourth electromagnet arranged in a magnetically repelled position relative to the third electromagnet.
