Electro magnetic field is a region that possesses electrically charged particles that forces the energy to pass through the region, affecting the electricity (Carroll).  According to Andrew Collins, a physicist who studied Crop Circles for long times, “99 percent” of Crop Circles “are man made creations,” however, “[a]ll the answers are not simply that people created them,” telling that supernatural power involved in the formation of Crop Circle (Brent).  The physicists claims that about 20% of the Earth is magnetic field and that creates a current that flattens the crops in its path, which explains the failure of electric equipment in the area of Crop Circles (Monstrous). Interferences of electro magnetic interference around the area of Crop Circles are consistently reported, adding the possibility of the Electromagnetic field theory (Pantherfile).  To prove the theory, Andrew Colins began his experiments by reading the magnetic forces in the area of Crop Circles using magnetometer finding the fact that the rate the force is increased by “approximately 120 percent” compared to other fields in the Earth (Pantherfile).  Although the logic of the Electromagnetic field theory is agreed by many people, the critics argue that if the theory was true, all the crops in the earth were consistently be flattened since the Earth is covered with magnetism.
