Where did Mars' magnetic field go ?

It is believed that the magnetic field of Mars that may have once made it possible for life to have survived there could have been lost due to a massive asteroid bombardment in the planet's distant past.

"If you've seen The Core then you know that the only thing between us and instant space-death is a magnetic field. You also know that's the only thing that's even heard of real science in the entire movie, but it's a pretty important one - and could explain why the otherwise eminently habitable Mars is such a barren wasteland."
