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
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.
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?
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.

You don’t need wires if the cement is conductive \s
Ah yes, the mad scientist way. Keep clear of the walls during storms though.
