Deep space radiation solution ?

[Pulpstar]

The way we deal with galactic (And especially solar) radiation here on earth is through the earth's magnetic field, and this is generated by the rotation of magnetic metals in the earth's core.

Would it be possible on a future spaceship/ark to generate a magnetic field in the centre by spinning iron incredibly quickly or some other method of generating a magnetic field to shield the craft in order to 'shield' the craft from radiation that may have a damaging effect on the occupants ?

Also the field could be varied as I'd guess there is less deep space radiation once you are significantly away from stars/large radioactive Jupiter planets (Say halfway between here and Proxima Centauri) than say 50,000 km from Mars ?

I think this in conjunction with more traditional shielding may be the answer although the technology/cost is probably outside of our lifetimes.

Has any work been done on generating magnetic fields to mitigate radiation ?
