Reducing occupant exposure to EMFs in residential construction: Avoiding AC magnetic field EMFs – Free CE Webinar
First to be discussed is AC magnetic fields. This is the type of EMF you think of when you hear the words, “electromagnetic field”. It has four common sources: separation of conductors carrying current loads, such as overhead power lines; unbalanced electric loads on adjacent hot and neutral conductors; current on grounding paths, including metal water pipes and TV cable sheathing; and point sources, such as transformers and motors.
Yet, magnetic fields are only one component of a duality of fields present wherever electricity exists, the other being electric fields. Electric fields will be discussed in a separate webinar.
