DIRAC`S DREAM: THE MYSTERY OF THE MAGNETIC MONOPOLE
... What would this look like? The electric field of an electron E = rq2 r̂ is a “hedgehog” with charge q and with strength falling off with the squared of the distance. We would then expect a magnetic monopole to produce a “hedgehog” magnetic field B = rg2 r̂. A bar magnet looks like two such monopoles ...

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.
