Chapter 27 Electromagnetic Induction and Faradays Law a changing magnetic field can produce an electric current! 1) Electromagnetic induction(电磁感应现象) The process to produce the current and emf is called induction 2) Induced current(感应电流) The current produced in the loop is called an induced currentChapter 27 Electromagnetic Induction and Faraday’s Law 1) Electromagnetic induction (电磁感应现象): The process to produce the current and emf is called induction. 2) Induced current (感应电流) The current produced in the loop is called an induced current. A changing magnetic field can produce an electric current!
