Q. What is EMF? A. Electric and magnetic fields (EMF) are invisible
... A. Electric and magnetic fields (EMF) are invisible lines of force that are present wherever electricity flows — around appliances and power lines, and in offices, schools and homes. Electric fields are created by voltage and shielded by most materials, such as lead, soil and concrete. Magnetic fiel ...
