Abstract

<p class="Abstract">The development of technology and the corresponding increase in living standards imply the generalized use of the most diversified and sophisticated equipment, a distinct, significant category being household appliances. The frequent presence of these devices close to a person’s heart, eyes, or brain naturally gives rise to concerns about the level of the associated (low-frequency) magnetic fields. The main objective of our paper is to study the possible correspondence between the low-frequency magnetic field generated by some household appliances and their current consumption. The proposed measurement system consists of the hand-held triple axis 480826 EMF Tester manufactured by Extech Instruments and the 80i-400 Fluke clamp meter. The performed measurement methodology takes into account the operating principles of the appliance. We perform measurements for a large selection of devices (47). The measuring point for the magnetic field is set at 30 cm from the source. Finally, by applying the Biot-Savart law to the previously determined drawn current, we calculate the magnetic field. We also compare the corresponding, directly measured values and analyze them.</p>
