I thought so, too. Upon a quick search, the most powerful magnet ever made on Earth is around 45 teslas, which according to WolframAlpha is 450,000 gauss. I'm assuming the difference is that these stars have the magnetic field strength everwhere on their surface and covering a huge region beyond the star, whereas the human made magnets, likely superconducting, only have that field strength in a very small area. That's just an intuitive guess though, as I don't know for sure.
