EVILS: WORD OF THE DAY! EMF: Electro Magnetic Field, or Electro Magnetic Frequency. As the name suggests, it's a combination of electrical and magnetic fields. You'll find high EMF levels around power sources, fuse boxes, electrical outlets, computer monitors, microwave ovens, etc. Unexplained EMF fields often indicate something paranormal. EMF fields can be measured with various tools, including an EMF meter or a hiking compass.~Grim
