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.

Once this spell is cast, is it possible for another spell caster inside the bubble to concentrate on maintaining a spell that exists outside of the bubble?
Can information from Arcane Eye (existing outside of the bubble) be received from another spell caster who is inside the bubble?
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.
I wonder what would happen to undead inside the field. Especially powerful ones like liches etc. Will they just temporarily disappear and then reappear? If so will they remember what happens in between?
Also what is with magic features of creatures, like only to be harmed by magic items. Will this persist even inside the field?
If you're talking about animate dead, the spell's duration is Instantaneous, so it can't be dispelled or suppressed.
That's not technically correct though.
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.
Seems to imply undead servants created by Animate Dead would wink out of existence.
I don't think Animate Dead creatures would kink out of existence. They have no reason to. The body isn't magic. It is a physical body. I think it'd be fair to say they loose their animation, though. But I believe its referring to things like Find Familiar and Simulacrums.
Like wise, an active body made using the Clone spell wouldn't be dispelled in an antimagic field. The spell merely makes the body, grows it, and protects it until a soul enters it.
It appears you are correct, according to Sage Advice

I stand corrected!
The one vaguely irritating thing to me is that the radius is so small. But I suppose that a dragon could technically still use it, as the radius uses you as a focal point, I guess it extends 10 feet from every point on the dragons body? My own feeling is that the spell is utterly useless for Player's but the effect description is useful for DM's to create areas of antimagic.
What would happen to a bag of holding in an anti-magic field? Would the items inside be permanently or temporarily lost? Violently reintroduced the physical plane?
Asking the real questions here, I'm curious too.
My take on it would be the bag would probably rupture and break unfortunately, depending on the objects within. Due to other editions I feel a bag of holding is treated differently in 5e than what its wording actually says. It makes no specific mention of the bag ever linking to an extradimensional space, only that the interior is considerably larger than its outside dimensions and that it weighs 15 pounds no matter the weight of objects inside it. It does say, "If the bag is overloaded, pierced, or torn, it ruptures and is destroyed, and its contents are scattered in the Astral Plane" so there is some connection to the Astral Plane at least.
With this in mind I feel the magic of the bag being suppressed would mean it's interior space is no longer considerably larger, and that everything within the bag is now trying to fit inside its actual physical dimensions. Since the contents being scattered in the Astral Plane is tied to its magical nature, I feel the contents would instead just spill out in your current space, or you end up with a bag that looks like a pin cushion or something similar!
If you're going with the extradimensional notion, where the bag acts as a portal to an extradimensional space, the argument could be made that suppressing its magic results in that portal disappearing temporarily and so access to the bag's contents is impossible. The items and the space they're in however continue to exist.
The way I would DM this is that the stuff inside the extradimensional space would be fine, but would not be accessible due to the bag not being able to function as a portal.
I would say that the portal to the extra dimensional space is suppressed, cutting off your access while in the sphere. And I know Critical role has ruled this when Bags of holding have been in Antimagic fields and within the vision of a beholder, if you put stock in Mercer's rulings.
That seems like least disruptive option. I could see some corner case alternatives, depending a additional aspects of the scenario. This could be one of those situations that helps to determine what kind of DM you aspire to be.
I'd probably bring this up (out of character) with PCs that have extra-dimensional items such as a bag of holding or a portable hole. s I have already followed that route in games I DM. For instance, when a PC acquires of those two magic items, I pull them aside an make sure they know that putting one or more of those items together would cause a tear in the fabric of Reality. (In nearly all cases I only tell them once, and then it's up to them to remember that they could potentially mess up and open a tear to the Astral Plane). In one case, one of our players was contemplating having two bags of holding. He'd keep with his equipment on his belt and an (empty) bag in his backpack. His ideas wast that in extreme situations he'd dump out everything in his main bag and then move quickly towards the BBEG and toss one bag into the other bag at the BBEG's feet and see what happens.
It never came to pass. The PC couldn't convince anyone to let him keep multiple bags of holding over the months, since other PCs wanted them for themselves.
But I thought I'd share....
heres a really specific but awesome use of this spell the dark wizard almighty is close to tpking the party the fight happens in a narrow corridor the druid goes behind the Dark wizard and casts antlife shell trapping the Darkwizard the monk closes in with the Dark wizard the cleric casts antimagic and field and closes in trapping the dark wizard the monk grapples him trapping him and starts beating the helpless Dark wizard to death
Edit: changed example to dark wizard
Could a wizard with this spell fall in a fissure of the Earthquake spell? Or would the fissure would just don't appear beneath him? (sorry don't know how to indicate a spell)
my take on it is that the bag functions as a portal to its storage demiplane, and therefore would temporarily be closed
Acererak, can you maybe not spam this spell?
What would this do to an artificer's infusion? Or for that matter things like their homunculus, arcane torrents and steel defenders? RAW I don't think this would effect an armorer's arcane armor but their armor is called arcane armor. So would an armorer temporarily lose their arcane armor?
I think they'd be unaffected by the Earthquake. If it created a permanent fissure that was no longer being sustained by magic then I think the wizard could fall in.
What a crazy spell, but it is 8th level
