Reply to comment by knightlife in can you run an ethernet cable through an empty conduit in your house on your own? by VanillianArt

Yeah, fish tape is flexible, yet stiff enough that it should be able to make it through multiple bends. Additionally - at least in the US - code requires there be no more than 360 degrees of bend in conduit between boxes. For exactly the purpose of being able to pull wire through it. It gets to be exceptionally difficult to pull wire past anything more than 360.

Anything more than that, and the original installer hated everyone else anyway. I’ve seen examples of what you saw in that video. Works awesome inside a wall with no insulation in the cavity. Works much less well when there’s insulation involved. And the amount of friction that’s inside of a conduit would almost certainly overwhelm the holding power of the magnet. Also, if it’s steel conduit (EMT, IMC, or rigid,) the conduit itself would also get magnetized.

You sure know your stuff! Thanks for indulging. I’ve vastly enjoyed running my wires through interior partition walls way more than my exterior walls with insulation (and blocking in one case! That was a nightmare!). I’ve just never run with conduit so wasn’t too sure about all the particulars. Who knows how OP’s conduit was installed but these are all great considerations to take into account.
