Colour me skeptic. No mention of its properties, or composition. Sounds like some dude put iron powder in cement and cried eureka!

A magnetic cement (mixed with iron) will indeed make it easy to hang a picture on the wall without a drill at the small small price of blocking mobile and wifi signal
Also when you have to drill into a wall (say, to get a cable through it), those devices that detect wires won’t be able to help you anymore. Sooo… Good luck?
You don’t need wires if the cement is conductive \s
And don’t need heating and lighting
Ah yes, the mad scientist way. Keep clear of the walls during storms though.
Well. To hang pictures and hooks it makes sense to have wall panels with holes or whatever. And not drilling bearing walls.
Small-small price might be even fine, it’s scary how we live in a world full of wireless connectivity. Just some wire between rooms, LOL.
Just - if attaching stuff with magnets isn’t generally common (except fridge doors), then making magnetic concrete walls doesn’t seem to have potential in helping with that.
When I saw that headline, I was thinking of something like concrete magnetic floors in space, something sci-fi.
Flying concrete from Earth’s gravity well seems very expensive, though.
If that’s not enough of a sell for you, how about rusting walls from any of that iron that finds itself on the surface
And let’s not forget concrete and steel are the most environmentally impactful building materials. Is “magnet” a good enough reason to fill your walls with them?
Wanted to ask exactly that - I don’t care too much about blocking wifi because repeaters are a thing, but mobile reception is gonna suck big time. If this is going to be widely adopted, we will be back in the times of searching the spot with the least worst reception.
AI slop in article, disregarded.
Test it to see how it does with cell phone signals because if it kills them then there’s a good chance that it won’t catch on because a lot of people use their cell phones indoors and things like Wi-Fi
If I use it in my bathroom grouting, do I make a Faraday cage?
How does it interact with EM radiation?
