Researchers propose technique for measuring weak or nonexistent magnetic fields

Wednesday, March 8, 2017 - 16:22 in Physics & Chemistry

Physicists at the University of Iowa have proposed a new technique to detect and measure materials that give off weak magnetic signals or have no magnetic field at all. Their solution would use a noninvasive probe to induce a magnetic response in the material being studied and then detect how that response changes the probe's own magnetic field.
