Hello all, I am trying to apply Faraday's law of induction to calculate emf. I know the cross-sectional area, number of windings, and the magn. flux density (B) as a function of time. So everything looks fine, except one thing. An aliminum cylinder is passing through the coil. In this case, can I still apply the faraday's law as it is, i.e.: EMF Voltage = d (B(t) . Area) / dt ? What will be the effect of the aliminum rod? I guess it will result in eddy current, but i am unsure if it s going to be approximately OK if I neglect the Al cylinder and use the above equation? Please see the below figure.
