Title of PAPER - Department of Physics and Astronomy

... This paper has shown that although it is possible to create a magnetic field with the same intensity of that of Earth’s on Mars, it would require an unfeasible amount of energy to do so. It must be noted that this energy is only to create the magnetic field, and that in event that this causes the cr ...

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.
