Hi David, Can you tell me where the following link has been moved to? <http://groups.yahoo.com/group/femm/message/1260> I am trying to use your FEMM to design a linear motion damper using eddy current induced on a shaft oscillating in a sinusoidal manner. The amplitude of the oscillation is 1.7mm. Have you done similar damper before? Any guidance that you can give me will be most appreciated. C F Cheuk
