Why hasn't anyone found a way to engineer magnets to attract different types of metal?

because there are not many combinations of unpaired VS electrons that can react to magnetic fields in a differentiable way.

I am intrigued because this is theoretically possible, but the end result wouldn't really be a "magnet" anymore, but a system that differentiates metals and then applies a magnetic field to them if they meet x requirement.

This is a robot + a magnet.

Unfortunately, we can't engineer a fundamental force of nature to do suddenly be selective

Already been done, and they're called induction motors.
