How does Dumbledore prevent Voldemort from getting the Philosopher’s Stone?
Dumbledore and Nicolas Flamel use powerful enchantments to protect the Stone. Most importantly, Dumbledore places a special spell on the Mirror of Erised: only someone who wanted to find the Stone but not use it could take it from the mirror. This clever protection ensures that someone greedy or evil—like Voldemort or Quirrell—could never obtain it. After the events in the chamber, Dumbledore and Flamel agree to destroy the Stone completely so that Voldemort can never use it to return to power.
