Rodger Boots is probably the one to ask, but I believe the core itself is
slightly deformed as you apply more or less of a magnetic field across it.
(The core in this case would be the yoke's core.)

It's the same thing that causes flybacks to squeal. The term "magnestriction"
or something similar comes to mind, as the name for this phenomena.
