H field vs e field
http://arrl.org/rf-radiation-and-electromagnetic-field-safety WebKey terms. A field models what an object would experience related to a force at a given point in space. A magnetic field is a field explaining the magnetic influence on an object in space. A electric field is a field defined by the magnitude of the electric force at any given point in space. Current is the rate of charge moving past a region.
