It's just an electromagnet, if you want more information, search on that.

An electromagnet, like any other magnet will attract differing poles, and repel similar. But an electromagnet has it's poles, and strength determined by the electricity flowing through it. More flow, a stronger field, reverse the flow reverse the field. So when it is next to the fixed magnet it'll either push away from it, or be drawn to it, with various strengths following the signal.
