Wands are used by witches and wizards to channel their magic powers and to cast spells. It is commonly thought that a wand increases magical ability but this is not true. A wand actually magnifies and focuses magic. This makes it possible to create very powerful spells. 

      There are many things to consider when finding the right wand. It really is not as easy as you might think. For the most part this process is based on trial and error. When making a wand for a specific witch or wizard the elements that are used generally show their character. However, the best results are usually happen when the wand chooses the owner.

      Mr. Ollivander uses four criteria to classify the wands. He describes the physical features of the wand by: type of wood, length and the core material. The quality of how the wand moves is the fourth section and is more personal.

      Only a single piece of wood is used the make each wand and at the center is a magical substance. The type of wood that is used to make wands often aligns with the date of birth, according to the Celtic calendar. Phoenix feather, dragon heartstring, and tail of unicorn are the three magical centers used by Mr. Ollivander.

      In the Celtic calendar, a tree represents each month, and each tree is connected with specific powers and qualities. For example, Harry Potter was born on July 31st. His wand is made of Holly, which occur simultaneously with his birthday. Holly is said to ward off evil, and is a symbol for protection. It also is seen as a sign of hope because, it is perennially green, and has bright red berries during the winter. Phoenix feather is at the core of the famous Harry Potter's wand.
