Hi,
I am completely new to the subject, and sorry if the question is too
basic. I will be very graceful if anyone would provide me with some
info,references. links to worked papers, or suggesting keywords to search
and my Major is in mechanics, on Finite Element Analysis area
the problem is whole simulation and the equations, not experimental

There is a piezoelectric coil (as sensor), which due to deflection shall
provide a change in magnetic field, (how can I find with which physical
equations this happens for example the change in magnetic flux, the
Ampere's law seemed not helping me in progresion). the next step is how this
field may be sensed with a macro device (again the principles) I have to
solve it parametrically to be able to design the coil.
