Freezing Charm

There is no incantation given for the Freezing Charm, and no direct effect either. According to Horace Slughorn, a Freezing Charm will disable a Muggle burglar alarm. It can be speculated that a Freezing Charm stops things form moving, or disables devices. It strikes resemblances to the Flame-Freezing Charm, which negates the effects of fire, and Peskipiksi Pestronomi (if real), that freezes Pixies.
