THEORY The magnetic flux (B) through a surface is the component of the magnetic field passing through the surface. OBJECTIVE To determine the Faraday’s law of electromagnetic induction using a copper wire wound over an iron rod and a strong magnet. Faraday’s law is a single equation describing two different phenomena: the motional EMF generated by a magnetic force on a moving wire, and the transformer EMF generated by an electric force due to a changing magnetic field.ĪPPARATUS REQUIRED -: Insulated Copper wire An iron rod A strong magnet A draw board for base/platform A light emitting Diode (LED) Opposite sides of an iron ring or ‘torus’ to induce current. In Faraday’s first experimental demonstration of electromagnetic induction, he wrapped two wires around Whereby an electric field is induced, or generated by a changing magnetic field. From natural phenomena, such as the light we receive from the sun, to technologies that improve our quality of life, such as electric power generation, Faraday’s law has a great impact on many aspects of our lives.įaraday’s law describes electromagnetic induction. Understanding Faraday’s laws of electromagnetic induction can be beneficial since so many aspects of our daily life function because of the principles behindįaraday’s law. The ability to quantitatively describe physical phenomena not only allows us to gain a better understanding of our universe, but it also makes possible a host of technological innovations that define modern society. These equations for electromagnetic induction are extremely important since they provide a means to precisely describe how, many natural physical phenomena in our universe and behave. Faraday explained electromagnetic induction using the concept of lines of force. It is the fundamental operating principle of transformers, inductors and many types of electrical motors and generators. INTRODUCTION Faraday’s Law of Electromagnetic Induction: It is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF). Without her motivation and help the successful completion of this project would not have been possible.
