The short answer is yes, poker chips are magnetic. The long answer is a bit more complicated. Poker chips are made of a soft plastic material and are filled with small iron pellets. The pellets create a strong magnetic field when placed near one another.
As a result, poker chips can be used to track the movement of other poker chips and also to keep track of who has won or lost a hand. However, because the magnetic field is weak, the chips cannot be used to store any information.
