PHYS 2092 Lab 5: Faraday's Law and Lenz's Law INSTRUCTIONS Introduction In this lab, you will explore several predictions of Faraday's Law and the implications of Lenz's Law in Electromagnetism. You will be using an online simulation on the PhET website called Faraday's Law: https:thet.colorado.edufsimsfhtml/faradays-lawflatesUfaradays-law_en.html Theory When a magnetic field B goes through a surface A (may that field be real or imaginary), we say there is a ux (1'3 through the surface. According to Faraday's Law, when a magnetic ux changes through a coil that has N turns in time t , the rate of change of the magnetic flux generates a voltage Em\" at the terminals of the conductor the coil is made of. This average induced voltage can be written as the following: NACD e = B coil At (5.1) To figure out the direction of the current through the coil, Lenz's Law is what we need to apply. According to Lenz's Law, when a magnetic flux changes through a coil, the coil generates an induced voltage such that the magnetic field associated with the current through the coil opposes the direction of the change in magnetic ux. We will use a concrete illustration to explain this phenomenon
