Sources of electric field. Causes and description. Electric fields are caused by electric charges or varying magnetic fields. The former effect is described by Gauss's law, the latter by Faraday's law of induction, which together are enough to define the behavior of the electric field as a function of charge repartition and magnetic field.
Answers. Best Answer: The following is in relation to an electromagnet, but generally applies to magnetic fields generated by electric current. The magnetic field is proportional to the current in amps and the number of turns of the conductor about the core (ampere-turns).nswers.
