@taichokage: Well I think that Zebura could possibly make him drop his force field by unleashing a powerful sound wave that would break his ear drums and distract him. Plus I think Zebura's attacks are on a level that could possibly break through his force fields arent they?
Last I read, Magneto was massively depowered along with Cyclops and Emma due to the phoenix force event, in the recent Uncanny X-men series. IIRC, all he could control without hurting himself were nails and metal scraps. I haven't read it as of late, so I don't know if this has changed. But if it hasn't Magneto is getting wrecked.
At normal levels though, Magneto stomps horribly.
