When a mechanical force is applied to a crystal causing it to distort, the
crystal produces an electric field.

This can be seen as a spark in the case of a piezoelectric lighter when a
hammer strikes the xtal.

My question, does the xtal loose anything of itself each time it releases a
spark.  As the spark is a stream of electrons, makes me think that the
crystal is loosing electrons.

However, intuitively, I think the it is not reducing or decaying and is
similar to introducing a magnetic field to a coil.  A current is induced in
the winding.

So then I ask the question, is the permanent magnet becoming less of a
magnet each time it is used to induce a current in the winding.

I am tempted to think the magnet does loose its magnetism but not sure.

What say ye.
