A demagnetized credit card will not work when you swipe it. Normally, the magnetic strip on your credit card can be read by a terminal to detect that it is valid and receive any information from there, but if the magnet was removed or damaged in some way then this does not happen. If you still want to use your credit card for purchases at point of sale terminals, first try using an old US dollar bill instead; they have no security chip so they will always recognize them as being valid even if their magnetic strips are fully removed.
