Spells that can be used on you are:
Telekinesis: pick up a large, mundane object outside the AM field and throw it at you. IIRC that is caster-level x d6 attack.
Wall of Stone/Iron: conjured right outside the AM field and toppled onto you.
Divinations: Depending on the GM, AM field may not prevent some divinations from providing information about you since an AM field is not a diety.
Darkness/Silence: the area not in the AMF is still dark which blocks any outside light so the inside of the AMF is probably dark, alternately silence blocks noise getting into/out of AMF.
Cloud spells: while any acid or solid aspect does not directly affect you, they still obstruct line of sight.
Earthquake: a small area around you is unaffected by the spell directly, however the ground beneath & and around that is still doing the hokey pokey. I might give a +2 to saves & concentration checks but maybe not.
Lower water: welcome to a hole in the ocean. I guess you'd be about 5' higher than normal.
Illusions: any not within the AMF will still be as effective against you.
Plant Growth: Overgrowth. The plants outside the AMF will grow to the entangling size and will impede movement.
Prismatic wall: AMF is specifically unable to penetrate it.
