You can't just say that.
I'm not just saying it, I'm basing it off his history.
Silver Banshees wail was magic and should have killed him, instead it put him in a coma. Generally, weapons magically enhanced for cutting will cut him, but the effect of other types of magic is a crap shoot.. It ranges from hurting him more than usual, to not really hurting him more than a non magical version of that attack. On average, for Post Crisis Superman magic = drawing some blood, but being far from putting him down.
It's simply too inconsistent to say Thor's magic hammer bypasses his durability, and lets Thor cause much greater damage than he does against anyone else.
