curse of royal vs field magic

[speonkcake]

If my opponent has a field magic card on the field and I play a field magic card on my side of the field, can my opponent chain curse of royal to negate the activation of my magic card and keep thier magic card on the field?

No. "Curse of Royal" only effects S/T that include in the effect to destroy 1 Spell/Trap. Technically activating a 2nd Field Spell I believe only sends the other to the Graveyard, but even if it does classify it as "Destroyed", that's only as a result of the play and not due to any specific effect of the card.
