I'm designing a test to measure the damping of sprayed-on ceramic coatings. The test will use free-free beams suspended in a vacuum chamber and excited magnetically. We will measure the response with laser vibrometry. My question is in regards to the magnetic excitation. Does anyone have a good system that is capable of producing a reasonably strong excitation source? We need to operate in the 50-2000Hz range. I've had a bit of problems finding manufacturers of electromagnets that could be used for this application.

Thanks,
Shad
