Electromagnetic fields (EMFs) are areas of energy that surround electrical devices and are produced by the movement of electric charges. They consist of two components: an electric field, created by voltage, and a magnetic field, generated by current. EMFs are present in various everyday items, such as cell phones, microwaves, and power lines. These fields can vary in strength and frequency, with low-frequency EMFs coming from household appliances and high-frequency EMFs associated with wireless communication. While most research indicates that typical exposure levels are safe, ongoing studies continue to explore potential health effects related to long-term exposure to strong EMFs.
