The magnitude may or may not be altered every time but the electric current must change its direction periodically. It is indicated by the abbreviation AC. The standard waveform of alternating current in most electric … Read more

Faraday’s Laws of Electromagnetic Induction – First and Second Law

Faraday’s law of electromagnetic induction (alluded to as Faraday’s law) is a fundamental law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF)? This concept is called electromagnetic induction. Faraday’s First Law Faraday’s First Law states that “Whenever a conductor is placed in a changing … Read more
