ABSTRACT This lab is performed to analyze and understand Faraday 's law of electromagnetic induction and also its application in different magnetic components using Faraday 's Electromagnetic Lab simulation software 2.07. In this lab we understand the properties of the bar magnet, the basic electromagnet and also the electromagnetic induction in transformers. In the basic electromagnet, we observe the movement of the electronics both in AC and DC current source and compare the movement of electronics in those conditions. For better understanding of the electromagnetic induction in transformers, we observe the brightness of the bulb by changing the number of the loops in the coil, varying the magnitudes of the input ac current and also varying frequency.

Faraday 's law: A time-varying current produces a magnetic field, and a time-varying magnetic field produce an electric current. The magnetic field intensity is linearly related to the current which produces it. The current can be produced by an alternating magnetic field and that a time-varying magnetic field can induce a voltage, or an EMF, in an adjacent circuit. This voltage is proportional to the rate of change of magnetic flux linkage, or magnetic flux, or current, producing magnetic field.[1] Faraday 's law of induction states that emf is induced whenever the magnetic flux linkage changes. We can also say that emf is induced in the conductor whenever the conductor cuts magnetic flux, and the…
