The Faraday effect outlined in eqn is a better format to apply to an MOCT, because the rotation angle in this case is directly related to the enclosed electric current. It rejects the magnetic field signals due to external currents which are normal ...

Understanding electric and magnetic fields
... Electric fields are created by voltage (the flow of power). Magnetic fields (the force of power being discharged while electricity is moved) are created by alternating current. To illustrate, an electric field will be present around a lamp that is plugged in but not turned on. A magnetic field will ...

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.
