Counterspell section of SRD states: "If the target is within range, both spells automatically negate each other with no other results."
Antimagic field description of SRD states: "Dispel magic does not remove the field, though Mage's Disjunction might."
I made this question because I'm unsure that a Dispel Magic could negate Antimagic field thanks to a Counterspell. If both spell come into existence and then negate each other, can a Dispel magic negate a no magic area? Or perhaps the spells negate each other before they even come into existence?
I think it's a problem of timing. Spells come into existance before they counter or not?
