Development of magnetic generator data acquisition system based on microcontroller for Faraday rotation instrumentation

Abstract

This research is performed to develop a magnetic generator to create magnetic field which has an influence in altering the magnetic optic, due to the produced magnetic field on a specimen among both groups of coil, which can be quantitatively investigated. The magnetic field uniformity among both groups was also investigated three-dimensionally. The magnetic generator contained of auxiliary coil, is reversed for each group and integrated toward a ferromagnetic material as the core for the magnetic induction amplification. The supplied current was set for up to 10A and produced 0.1T. This can be monitored by microcontroller-computer communication protocol. The produced magnetic generator is going to be applied for another research to produce magnetic field for an instrument of Faraday rotation. This study produced a transfer function B vs. I with B = 98.2650 I + 18.2732.This research is performed to develop a magnetic generator to create magnetic field which has an influence in altering the magnetic optic, due to the produced magnetic field on a specimen among both groups of coil, which can be quantitatively investigated.
