An NS5-brane has five spatial dimensions and is magnetically charged under the Neveu–Schwarz two-form. Its string-frame brane tension scales as .
An NS5-brane, or Neveu-Schwarz five-brane, is a type of extended object in string theory. Branes, which are short for "membranes," can exist in various dimensions, and they play a crucial role in the framework of string theory, particularly in understanding non-perturbative aspects of the theory.
