THE APPLICATION OF ARDUINO MICROCONTROLLER AND FORCE SENSOR IN FABRICATING AN APPARATUS EXAMINING MAGNETIC FORCE ACTING ON A CURRENT-CARRYING STRAIGHT WIRE
Main Article Content
Abstract
An apparatus, which is fabricated by using Arduino microcontroller and force sensor, is used to examine the magnetic force on the current-carrying rectangular wire frame caused by the magnetic field generated by a U-shaped electromagnet. This apparatus can measure the magnetic force automatically and continuously with less than 10% error between theory and experiment. The Arduino microcontroller is programmed to rotate the electromagnet around a fix axis, i.e. changing the angle formed by the direction of the magnetic field and the electric current. However, the force sensor has not been optimal in below 2,5mN force regime and the data acquisition has not been fully automated. Once these limits are overcome, high-school teachers can use this apparatus to develop students’ competencies in Physics grade 12 of General Education Program 2018.
