For other uses, see EMF (disambiguation). Electromotive force, also called emf (denoted E {\displaystyle {\mathcal {E}}} and measured in volts), is the voltage developed by any source of electrical energy such as a battery or dynamo. It is generally defined as the electrical potential for a source in a circuit.
What is EMF? We live in an invisible sea of electromagnetic field radiation. Subtle energies constantly swirl in and around our bodies, whether or not we are aware of them. Electromagnetic Fields (EMF) are energy waves with frequencies below 300 hertz or cycles per second.
