i mean the answer is correct but it has nothing to do with what you are saying, the magnet could be 100x stronger and he still wouldn't move. it's because the magnet pulls the same force at the helmet as the helmet pulls on the magnet, and since they are part of the same system nothing will happen, it's like standing on rollerblades and trying to push yourself with your hands, it doesn't work.
