The magnets at the LHC are strong enough to cause protons with an energy of
6.5 TeV to bend into a curve with a 2.7 mile radius, you'd need
something stronger to protect a spacecraft, you'd need something that would
cause them to form a curve with a radius of just a few hundred feet. And
although rare some cosmic rays are MUCH more powerful than 6.5 Tev. And
magnetic fields would be no help at all against X rays or Gamma rays.
