Are punches with Gauntlets of Ogre Strength magical, improvised weapon attacks?

My Gnoll Paladin just got the Gauntlets of Ogre Strength from Phandelver the other day, and it got me wondering:

  1. Would it be possible/make sense for punches using them to count as an improvised weapon? (Since I’m not punching with empty fists, I’m wearing magical gauntlets)
  2. If so, would punches from a person using them count as magical weapon damage?
