A deliberation on the limits of the validity of Newton`s third law
... Now, considering that the situation related to the above-mentioned third question, as we saw, establishes Newton’s third law, we conclude that we must distinguish between the magnetic field arising from magnetic static poles (eg the magnetic field due to the poles of a magnet) and a magnetic field ...

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.
