Figure 4 This cross-section of a cylindrical magnet shows the flux density it produces. The 3-axis probes The 3-axis probes—whose sensors simultaneously measure the field strength across the x-axis, y ...

Hall-effect switches and instrumentation-grade sensors have become more commonplace in industrial applications, with a wide range of Hall-effect devices now packaged for designers of products and ...

By using sensors that measure magnetic flux density, the amount of current generated can be monitored noninvasively, which can signal a problem.

Physicists have developed a minuscule instrument able to detect extremely faint magnetic fields. At the heart of the superconducting quantum interference device are two atomically thin layers of ...

Investigating solar corona structures has led Paul Bellan, Caltech professor of applied physics, and his former graduate ...

A method is developed and tested by which magnetic-field strengths and area filling-factors of magnetic regions on late-type stars may be inferred from high-resolution, absorption-line profiles that ...
