Just had a random thought, what would happen if one were to drill recesses in to a door frame and flush fit large 800 pound pull magnets in to it and bracket them into the studs somehow so that the doorway was a ring of super magnets?

What happens when an armed home invader tries to come through the door?

Electric magnets? Otherwise how are you going to disengage them?

if you put magnets all the way around the net pull would be zero

in the exact center anyway

What would happen to you when you walked through it?   Everything you would plan on passing through that door would be non-magnetic???  Not so much!

I had a 6" high power puck rare earth magnet sitting on a rolling shop chair drag the chair after me coming after my 1911 from about a foot and a half away...
Depending on the "reach" of the field, either absolutely nothing, because the metal of the intruder is too far away, or conversely it'll suck them in like a MRI eating guns in a movie.





Here's a great video of MRI's eating shit under test.

Magnets is always the right answer. Except maybe in this case.

Not so much.   Most likely scenario is a) you kill yourself trying to install the second or third magnet.  b) you wipe all the cards in your wallet c) you randomly trash  laptop hard drives that go through the door.

No way you could install a field strong enough to immobilize a gun.  No. Way.

Creating a field strong enough to do it would be a piece of cake IMHO.





Getting the field to project a usable distance is what I think would be the hardest part.

Yeah, would need to be a very narrow doorway. Very narrow.

The idea is not to disable the gun, just the asshole with it, hard to use it if it's glued to the wall.

Bonus points if it tears off some fingers in the process.

Great idea. Better use a plastic or wood door (and door hardware) and never use the doorway yourself.

In before the OP tries it, and it works great.

But we never know about it because he wiped every hard drive within 3 blocks of his house, and he can't buy another because his credit cards are useless and his car keys are stuck to the door frame.

This would not stop someone from shooting you through the door as most ammo is made from lead and copper, non ferro-magnetic metals.



and uncle Sam is taking your M855s away so don't count on the magnets stopping steel cored bullets

Door willl neverr open because the lock mechanism will be stuck by the maagnets.  Intruders get pissed and smash first floor window.

I have thought about using a magnet to slide a bar across a door after its closed.

ITT we learn who knows that electromagnets are not magnets all the time, as well who's reading comprehension lets then understand the actual intent of the OP to "disable" a firearm does not mean making it not shoot, but orientating it in an unusable position.

The same thing that would happen if anyone enters your house with any metalic or attractive object, keys, legal carriers, metal medical implants, etc.  Poor fucken handyman.

Here's an article from the American Journal of Roentgenology wherein some dipshit took his sidearm into an MRI and caused a couple of million dollar$ damage to an MRI leased by General Electric to a hospital.

IIRC, the owner (GE) wanted to sue the Rochester, NYPD for damages, while the PD argued that the liability was with the officer alone. Of course, GE knew that Barney Fife would never be able to pay to repair the machine, even if he lived 100 lifetimes.



ETA: Other articles said the MRI operator refuted the officer's statement that they had allegedly told the officer to take it into the MRI room with him. The MRI operator said they had told the officer to leave his sidearm in a locker provided by the hospital, but the officer thought he was the only one "profeshunul enuf" and decided to keep it with him instead of leaving it in the locker.

Ok, so we need to replace our doors with a hobbit-sized round doorway that all visitors must crawl through



We fit our electromagnets, strong enough to suck a metal object to the side to make it unusuable, and configure the system so they are permanently on unless we (temporarily) disable them to pass through the doorway.



How much is the electricity going to cost to keep this magnet-based security system running for... well, probably about 23 1/2 hours a day?

Ever been near an 800 pound pull magnet?  The door does not need to be a rabbit hole, it would have a range of at least 2 to 3 feet from each side.

Maybe ring was the wrong word, I jest mean magnets along each side, though up and down could be interesting too.

The electricity bill should not go up at all if done right.  ALL charged wires have induction,that's how electro magnets work, so the power going to the house already could, potentially, be enough, though admittedly I have not run the numbers.  Simply wrap the normal house wiring around the rods to form the coils, the wires are their anyway, as well as the induction, why not put them to use?  To go through the door, simply turn off the breaker.

Alternatively, if that were not possible, one could simply create a dedicated circuit just for the magnets, but wire it to be always off, unless armed and triggered by a motion sensor, or other system, could just be as simple as setting the switch as a relay on a normal home alarm.  Alarm goes off, magnet goes on, when the alarm is not triggered the magnet consumes zero power because it is turned off.

Gonna find out the hard way about how little steel it takes to rip that bitch out of your hands when it comes to man sized magnets.





Even the aluminum of the receivers would be effected.
