Abstract

One of the quantities of fundamental importance in describing magnetic phenomena and materials is the magnetic moment. This research focused on the development of a paramagnetic materials analyzer using locally sourced materials to determine magnetic moment of magnetic materials. This involves the design of a sensing unit. The sensing unit comprised of a colpitts oscillator, preamplifier and shaping circuit, K – type thermocouple sensor, thermocouple amplifier, microcontroller, matrix keypad and a LCD. The developed instrument was calibrated using a known standard magnetic moment value of iron. The instrument was tested and it was able to determine the magnetic moment of available magnetic materials with a standard deviation of 0.0163. The value of magnetic moment obtained for the available known materials fall within the range of values obtained from literature.

Keywords: Magnetic moment, paramagnetic materials, oscillator, temperature, microcontroller and amplifier
