Hey poilbrun matey! 
I prefer the idea that either it blocks effects altogether or suppresses to some extent (and would be overcome through a metamagic feat). Otherwise it just becomes pointless.

poilbrun said:Such an interpretation could explain an upper limit for the effectiveness of an anti-magic spell. If you put a cap to the effectiveness of an anti-magic field (for example, any effect with a CL 5 higher than the the CL of the anti-magic field still works), you can easily explain it: the ability to cast higher level spells is simply the ability to use more magical energy, energy that lower-level casters can't even see. Gaining levels is just gaining the ability to tap more into that magical energy around you. When a spellcaster casts anti-magic field, he actually severs the access to the magical energy he can see around him. Faced with a anti-magic field cast by a 15th level wizard, a 25th level wizard would just say "well, kiddo, you forgot this and that bit" and cast his spell normally.
I hope this makes sense, I'm not sure either when I reread it, even though it's crystal clear in my mind.
