Electric field is present in the surrounding a charge transfer charge and charge interactions between physical field. In the total electric field surrounding a charge and electric field effects on other charges in. Observer observed when compared to static electric charge field is called electrostatic field. If the charge moving relative to the observer, in addition to electrostatic field outside, there are magnetic fields appear. In addition to charges that can cause outside the farm, changing magnetic fields can also be caused by an electric field, the former for electrostatic field, which is called Eddy electric field or electric field. Changing magnetic field causes an electric field. So between moving charge or current role to be passed through the electromagnetic field.
