Some matchstick heads contain iron(III) oxide as a colorant. The yellowish color of the burning match indicates that it has low oxygen, i.e. a reducing flame. It reduces the iron oxide to iron which isattracted by the magnet.

The red matchstick head is made from iron oxide and under normal circumstances it is not magnetic. So that's why you would of observed the unused/fresh matchstick not sticking (attracting) to the magnet. But when the matchstick is struck and burnt, it produces pure iron, which is magnetic.
A simple equation for the reaction would be:
Iron(III) oxide + carbon → iron + carbon dioxide
SO when the matchstick is burnt, it undergoes a chemical reaction, turning the red head (iron oxide and carbon) into iron and carbon dioxide gas.
The iron produced is what causes the matchstick head to attract to the magnet. This trick is more than a magic illusion... it's SCIENCE!
Hope it help.
