About: W. Wilson Dip Needle
Handmade in London in the early twentieth century, this device was used to measure the angle between Earth’s magnetic field and its surface, which varies based on location. When the metal disc is positioned vertically, the needle is prevented from pointing towards the magnetic poles and will align itself with the nearest magnetic field.
