The Role of Ions in Body Chemistry Negative Ion Report: The CBS
... Moving a wire relative to a magnetic field produces an Electro Motive Force which tends to drive a current (ie. Flowing electrons) within the air in a direction at right angles to the magnetic field. This relationship is involved in all electric motors and generators. The ion is an electrified parti ...

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.
