A 10-foot-radius invisible sphere of antimagic surrounds you. This area is divorced from the magical energy that suffuses the multiverse. Within the sphere, spells can't be cast, summoned creatures disappear, and even magic items become mundane. Until the spell ends, the sphere moves with you, centered on you.
Spells and other magical effects, except those created by an artifact or a deity, are suppressed in the sphere and can't protrude into it. A slot expended to cast a suppressed spell is consumed. While an effect is suppressed, it doesn't function, but the time it spends suppressed counts against its duration.
Targeted Effects. Spells and other magical effects, such as magic missile and charm person, that target a creature or an object in the sphere have no effect on that target.
Areas of Magic. The area of another spell or magical effect, such as fireball, can't extend into the sphere. If the sphere overlaps an area of magic, the part of the area that is covered by the sphere is suppressed. For example, the flames created by a wall of fire are suppressed within the sphere, creating a gap in the wall if the overlap is large enough.
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.
Magic Items. The properties and powers of magic items are suppressed in the sphere. For example, a longsword, +1 in the sphere functions as a nonmagical longsword.
A magic weapon's properties and powers are suppressed if it is used against a target in the sphere or wielded by an attacker in the sphere. If a magic weapon or a piece of magic ammunition fully leaves the sphere (for example, if you fire a magic arrow or throw a magic spear at a target outside the sphere), the magic of the item ceases to be suppressed as soon as it exits.
Magical Travel. Teleportation and planar travel fail to work in the sphere, whether the sphere is the destination or the departure point for such magical travel. A portal to another location, world, or plane of existence, as well as an opening to an extradimensional space such as that created by the rope trick spell, temporarily closes while in the sphere.
Creatures and Objects. A creature or object summoned or created by magic temporarily winks out of existence in the sphere. Such a creature instantly reappears once the space the creature occupied is no longer within the sphere.
Dispel Magic. Spells and magical effects such as dispel magic have no effect on the sphere. Likewise, the spheres created by different antimagic field spells don't nullify each other.

Does a dragon's breath count as magical for the purposes of this spell?
I don't think that breath weapons are spells/magic, unless they're from something like the spell Dragon's breath(xgte)
Paladin abilities are also suppressed? Like smite wouldn't work and you could get a disease?
That's a tough one. I would rule yes it was suppressed, but I could also see a strong argument for no. I would say getting a disease probably wouldn't be, but smites are pretty fantastical and even charged by spells although they aren't a spell. Tough one, and I don't see a Sage Advice addressing that specifically.
i'd say smite dosn't work, but they are still immune to disease
It’s correct. Besides, if it were correct they would just deanimate (and no I don’t care that’s not a word. It should be.)
like this: [ spell ] spell name [ /spell ]. Remove the spaces.
Nothing in the game is magical unless it's specified to be.
Would magical abilities like Wild Shape or breath weapons work in this field?
Curious about this myself, as well as Monk abilities as the use of ki does not specifically state it’s magical.
Wild Shape yes, breath weapon no.
what about a night hag's Nightmare haunting:
Nightmare Haunting (1/Day). While on the Ethereal Plane, the hag magically touches a sleeping humanoid on the Material Plane. A protection from evil and good spell cast on the target prevents this contact, as does a magic circle. (Emphasis mine)
Yeah, as written AMF would be protection from nightmare haunting. It both prevents planar travel (So the hag wouldn't be able to get in from the ethereal plane) and targets inside can't be the target of magical effects (so even if she did, can't target the guy.)
Having said that, AMF is a concentration spell so you can't maintain it while sleeping, and it only has a 1 hour duration so it would have to be re-cast regularly unless there's some worldbuilding stuff where a whole zone is AMF warded.
Additionally, Hags specifically are kind of an iffy example because lorewise, Hags break the rules of magic as it's understood. She could have something grody like a magic maggot that can craw up your nose and nightmare you from inside your head, or have a kind of magic talisman that lets her ignore AMF entirely.
But, back to your original point, yes. AMF would suppress a hag Nightmare haunting while the sleeper is inside it.
Fun fact: in older editions, psionicists were considered to project their own Weave, and not even gods/esses of magic could stop them from casting spells. And clerics/paladins/druids/rangers get their magic from divine sources, which don't necessarily rely on the Weave. Since this spell effectively states that it disrupts the Weave within the sphere, the DM could house rule that these casters are unaffected by this spell.
Giant with a bunch of very strong bags attached to his armour each containing a goblin mage casting this
'wizard "I cast fireball at the giant"'
'DM "No"'
do you think this would suppress the vault door in Waterdeep dragon heist it says you can't circumvent it but just casting this spell does not circumvent it
Would an antimagic field have any effect on the bladesong class feature?
This should suppress a Wall of Force or a Forcecage, right?
yep
