When you calculate the strength of those fields Gordon you find that the energy generated damages you as badly as the incoming radiation. Where do you store the fuel to generate such collosal energy that it can deflect a proton from hitting your ship at 99.999999999 % of the speed of light.
Best you discuss this with Dr Jeffrey Hoffman of MIT who is heading a NASA sponsored research team on shielding using superconducting magnets. This is of course just one avenue NASA are exploring; there are more conventional ones as well.
Surround yourself with thirty feet of water and you are safe. How do you do that in space ?
NASA are currently researching the feasibility of just such a scenario but using liquid hydrogen fuel as well as water.
Have a look at all the information freely available or maybe contact NASA for links to ongoing projects. Best of luck.
