LoL. And you think it doesn't. What's your problem? Using two wire rods does detect. I've put up more than you have. You got nothing but shit. Here it is again from the abstract of the scientific paper.

Correct. Holding two sticks or wires in your hand and walking around waiting for them to tug or cross each other is not a functional magnetometer.
