Not magic (or trick) braid, has billets sewn over the braided ends. With magic braid, there wouldn't be any billets sewn on top the braid.
Looks like an 8 strand flat braid. Bruce Grant's Leather Braiding book has examples of 6, 7, and 9 thong flat braids. His Encyclopedia of Rawhide and Leather Braiding has the same flat braids. Both books are well worth the money if you are interested in braiding.
There are lots of YouTube videos available as well.
