	Funding: This work is funded by the U.S. DOE under grant number DE-FG02-13ER41967, and by the U.S. DOE under contract number DE-AC05-00OR22725 with UT-Battelle Corporation. The first step in the three-step laser assisted H⁻ beam stripping for charge exchange injection is to remove one electron in a strong magnetic field. In order to preserve the beam emittance for the subsequent laser induced stripping of the second electron the magnetic field has to have large gradient of about 40 T/m along the beam trajectory. The required magnetic field strength for stripping 1GeV H⁻ beam is 1.2 T in 29 mm aperture. In order to allow for undisturbed passage of high power beam during the nominal SNS operation the stripping magnet made of permanent magnet material resides in vacuum chamber and can move in and out of the beam line. This presentation describes requirements and design and the magnetic field calculation results for a stripping magnet for the Laser Stripping Experiment at SNS.
