Moving Electrons
... If you were to make an electromagnet by using a straight wire (without loops), how would it be different from the coiled electromagnet you made? A cassette tape can lose its sound quality when it is left in a hot car or when the tape becomes stretched with wear. Why is the sound quality affected? Ho ...

It is worth noting that the current corresponding to 1lh-1e is actually contributed by not only the 1lh-1e transition but also the 1hh-1e transition. As shown in Fig. 2(a), the ACPGE currents reverse the sign from the left to right side, just ...

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.
