Study and Development of Electromagnetic Induction Laboratory

Abstract

The study and development of electromagnetic induction laboratory have three main parts; induction voltage measurement, magnetic field measurement and the speed controls of the coils loop. The measurement and controller were performed with Raspberry Pi board. The result showed the induction wire loops speed controls was 0.002-0.007 meters per second by controlling a DC motor. The magnetic field measurement can be measured in the range of 0-170 mT. The average of magnetic field of the apparatus which has 2, 3 and 4 pairs of the cylinder magnets were 13.0±0.9, 18.7±1.2 and 25.8±1.0 mT respectively. The average of induction voltage of the coils loop width of 2, 2.8 and 4 centimeter with maximum magnetic field and maximum moving speed were 39.33±0.35, 55.44±0.51 and 77.37±0.97 µV respectively.
