Can I use Catapult to hurt an Archmage who is in his Antimagic Field?

Antimagic Field:

Target: Self
Range 10 feet

Catapult's trajectory is quite unnatural:

The object flies in a straight line up to 90 feet in a direction you choose before falling to the ground

This makes me think that magic does not just fling it, but it is working on it until impact.
However, it could also be just a simplification on the creator's part.

It should be possible, as long as the object you choose is located outside the antimagic field.

Targeted Effects. Spells and other magical effects, such as majic missile and charm person, that target a creature or an object in the sphere have no effect on that target.

Catapult spell is instantaneous, the only magic is used on the object to launch it in chosen direction. It is not concentration sustained as telekinesis. According to the description, the projectile stops if it impacts against a solid surface. It is not a magical effect but pure physical force.

Still, if the caster would be able to cast 8th-leveI abjuration spell, a simple wall of force in a shape of dome, located just outside the antimagic field.

The answer from Wizards of the coast:

Thank you for contacting Wizards of the Coast. As long as the spell is within the weight limits. The spell is not a continuous spell it is a one time spell that launches a object. If you have any questions or concerns please feel free to contact us again at your earliest convenience.

    \$\begingroup\$ What question is the quote from WotC asnwering exactly? I do not understand why the weight limit and whether it is continous is relevant to András' question. \$\endgroup\$ – Ruse Sep 30 '18 at 16:21

It doesn't hit.

The damage and trajectory of the object are tenants of the spell since they are in the spells description. This part of the Antimagic Field spell cancel them:

Spells: Any active spell or other magical effect on a creature or an object in the sphere is suppressed while the creature or object is in it.

While Catapult is instantaneous, this feature only conscribes the limit of the spells effect, not the other magical effects the spell creates.

Many spells are instantaneous. The spell ... can't be dispelled, because it's magic exists only for an instant

(PHB 203, emphasis mine)

Only the spells effect is nonpermanent. Other magical effects may last. Another instantaneous spell that has lasting magical effects is Create Undead (PHB 229). An Antimagic Field would also affect the ghouls summoned as the control over them is magical in nature.

    \$\begingroup\$ A parallel may be an arrow fired from a magic bow. The magic bow starts the path, but the arrow is physical and would fly through the AMF to its target. No magical damage from the arrow, but mundane would be delivered. \$\endgroup\$ – NautArch Feb 17 '18 at 15:30
