Do EMFs exist indoors and outdoors equally?
Medical experts recommend adhering to international safety guidelines for EMF exposure, which are set well below harmful levels. As a precaution, they suggest practical steps like using speakerphone or hands-free devices to increase distance from your phone. However, they consistently affirm that based on current scientific evidence, low-level EMF from everyday devices is not proven to cause health harm.

What role do EMFs play in nature?
In nature, EMFs are vital to life and environmental balance. The Earth’s magnetic field, a natural EMF, shields the planet from harmful solar radiation and helps guide migratory species. Sunlight, another form of EMF, provides the heat and energy necessary for ecosystems to thrive. Some animals, such as sharks and rays, even use special receptors to detect faint natural EMFs emitted by their prey. These natural electromagnetic fields are essential for survival and planetary stability.

How were EMFs first discovered?
Electromagnetic fields were first discovered in the early 19th century. In 1820, physicist Hans Christian Ørsted observed that an electric current in a wire could deflect a nearby compass needle, revealing a connection between electricity and magnetism. This groundbreaking finding led to the development of classical electromagnetism, later mathematically described by James Clerk Maxwell. Their combined work laid the foundation for modern physics and our understanding of how EMFs function in both nature and technology.
