Electromagnet support system

A method of supporting a vibrating first object with respect to a second object, said method comprising the steps of:

• using an electromagnetic device to apply a magnetic force between said first and second objects;
• elastomerically supporting said electromagnetic device with respect to said second object;
• and
• controlling said electromagnetic device as a function of the position of said first object with respect to said second object and as a function of the position of said electromagnetic device with respect to said second object.

A system for supporting a vibrating object, said system comprising:

• an electromagnet for applying a net magnetic force against the vibrating object;
• a compliant structure for supporting said electromagnet with respect to a second object;
• a first control loop for controlling said electromagnet as a function of the position of the vibrating object with respect to the second object;
• a second control loop for controlling vibrations of said electromagnet;
• and
• a controller for simultaneously operating said first and second control loops.
