Magnetic Effect of Electric Current
... magnetic field and a conductor. When a conductor is set to move inside a magnetic field or a magnetic field is set to be changing around a conductor, electric current is induced in the conductor. This is just opposite to the exertion of force by a current carrying conductor inside a magnetic field. ...

... Magnetic fields are created when an electric current flows. Magnetic and electric fields then exist together. The greater the current the stronger the magnetic field. Magnetic particle inspection involves the generation of magnetic fields to locate defects in ferrous materials. It has been used for ...

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.
