Question

What are you doing how are this neemuch mention two applications of eddy current?

Answer 1

1.) Eddy currents are used for braking,since there is no contact with a brake shoe or drum, there is no mechanical wear . however an Eddy current brake cannot provide a "holding" torque and so may be used in combination with mechanical brakes.
2.) Repulsive effects and levitation in a varying magnetic field the induced currents exhibit diamagnetic like repulsion effects. a conductive object will experience a repulsion force . this can lift objects against gravity
