Electrical Magnetic Fields


Everyone in our modern society is exposed to the electric and magnetic fields (EMFs) that surround all electric devices.
Electrically charged particles have a region of space through which energy passes. This region of electric energy or energy force is known as electromagnetic field (EMF).Electromagnetic field exists wherever there is energy flow. This includes power lines, electrical wiring and other electrical appliances in the household and the workplace .Household appliances such as electric blankets, hair blow driers, televisions, sewing machines and microwaves are believed to be the most dangerous sources of electromagnetic fields in the household .People are exposed to approximately 0.05µT field strength in their homes .EMF strength decreases with increasing distance, therefore the EMF of household appliances usually becomes negligible at distances greater than half a meter. Exposure to household EMF is generally short (time taken to blow drying one’s hair) and controlled in comparison to the period of exposure from power lines.[1]

The electromagnetic fields were also found to affect the rate at which chemicals travel throughout the body, alter the signaling and replication of cells, the functioning of the immune system and the calcium uptake. Exposure to electromagnetic fields is believed to cause the release of hydroxyl ions and cause oxidative reactions that can initiate the development of cancer .A research found that children with leukemia were more than twice as likely to have lived in homes near high current power lines, where the electromagnetic fields were stronger.[5]


The understanding of a few simple physical concepts is important to the discussion of any interaction between external physical agents and biological systems. Surrounding any wire or conductor that carries electricity, there exist both electric and magnetic fields, collectively referred to as electromagnetic fields, or EMF. These fields often extend...
