In 1962, B. D. Josephson developed the Josephson junction. This directly led to the invention of the SQUID. Today, SQUIDs are widely used both in physics and many other areas where the accurate measurement of small magnetic fields is necessary.

We examine the theory behind superconductivity and the Josephson junction and expand this knowledge to include the different types of SQUIDs. We investigate methods of SQUID production and some of the materials used including the newer high temperature superconductors. Finally we consider the logistical problems surrounding SQUIDs and how they are used in physics, medicine and geophysics.
