Paper Abstract

Based on the strong magnetically induced birefringence and the magneto-optical absorption characteristics of dense ferrofluid thin films, this paper deals with research of their applications for magnetic field and electrical current sensing, using fiber optics. Preliminary experiments show the sensitivity of the system for magnetic field measurement (delta) H is better than 0.1 Oe, and for current measurement (delta) I < 1.2 A with a minimum detectable current threshold 6.5 A, which shows a promising potential for practical applications.
