Google ai: In an EMF detector, MF stands for Magnetic Field. It is one of the three primary types of radiation measured by multi-field detectors, alongside Electric Fields (EF) and Radio Frequency (RF). [1]Yes, ELF is related to MF. ELF stands for Extremely Low Frequency. When an EMF detector measures MF, it is typically detecting ELF-MF (Extremely Low Frequency Magnetic Fields), which are emitted by everyday household items, power lines, and electrical appliances operating at 50 to 60 Hz.
