Some Aspects of Mean Field Dynamo Theory - Indico
... A dynamo can be thought of as a mechanism for “closing the loop” between poloidal and toroidal fields. Velocity shear (differential rotation) naturally generates toroidal from poloidal field. The α-effect of mean field electrodynamics can complete the cycle and regenerate poloidal from toroidal fiel ...

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.
