Magic might be required, but you can kinda sort of imagine a tortuous path
to getting microwave energy, running a computer programmed gizmo, balancing
heating vs stirring power somehow would be tough...

It's all so much easier to imagine a time slicing do this, do that, do this,
do that kind of machine without much magic required. You'd use a no-permanent
magnet stir bar -- just paramagnetic iron with a plastic wrap. Move that for a while with
magnetic fields, stop that, blast with microwave energy field, stir again, repeat while necessary.

And sure, Arduino IDE can be used to develop it.
