Global Circuit Overview
... Gauss’s Law: The total electric flux through a closed surface is equal to the total net charge within the surface. In other words, if a closed surface of any shape is constructed in a region in which an E field is present, the surface integral of the normal component of the E field over the surface ...

Scanning SQUID microscope
A Scanning SQUID Microscope is a sensitive near-field imaging system for the measurement of weak magnetic fields by moving a Superconducting Quantum Interference Device (SQUID) across an area. The microscope can map out buried current-carrying wires by measuring the magnetic fields produced by the currents, or can be used to image fields produced by magnetic materials. By mapping out the current in an integrated circuit or a package, short circuits can be localized and chip designs can be verified to see that current is flowing where expected.
