Is there any possible way to charge a metal with only one type of charge i.e lets say iron to a negative charge; and have it only sustain a negative charge and still responds to magnets like a + attraction or a - deflection. Would love examples or videos upon the subject. Thank you :D

In your question you are mixing two different concepts of physics. The electrical charge state of an object is separate from it's magnetic characteristics.

If you magnetize an iron rod it will have both a "north" and "south" magnetic pole. A magnetic object always demonstrates these two poles. You cannot magnetize something and have it demonstrate a single magnetic pole. Also, the process of magnetizing it will not necessarily give it any electrical "charge". If you do apply and electrical charge to it, and the object is highly conductive, like an iron rod, it will be only positive or negative, and will have no reasonably perceptible effect on the magnetic properties of the rod.

Perhaps if you tell us a bit more about what you would like to accomplish or demonstrate, we can help you better.
