The invisible energy fields known as electromagnetic fields (EMFs) are connected to electricity and other types of artificial and natural illumination. Although extended exposure to some EMFs can be harmful, some EMFs are safe. People may measure and see these fields in their surroundings by building a basic Arduino electromagnetic field detector. Electric charges in […]
