Scotty Cameron studio newport putter may be a fake because it is magnetic?

I won a scotty cameron in a raffle and i did the magnet test to see if it was a knock off. I put the magnet up to the bottom of the putter head, and to the face and it sticks to both. i swear the putter is so convincing otherwise. i was wondering if there are magnetic studio newports because I went to titleist website and everything is identical--or at least seems that way.
