Magnetic Levitation
... Take a look at the levitating pencil again. I lined up all the south poles so they would repel each other, which makes the pencil levitate. Pretty cool, huh? Another type of magnet is called an electromagnet. When an electric current is run through a wire, it produces a magnetic field To reverse the ...

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.
