... Note: Some texts use a “left-hand” rule and the electron current. If the wire is formed into a loop, the magnetic field around all parts of the wire contributes to the field in the middle of the loop, making it stronger. The magnetic field increases as we add more loops (solenoid). The field inside ...

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.
