PHY 1520 - Activity 5: Chapter 23 - Faraday's Law and Inductance For all problems, please show explicitly the work that you have done to arrive at your answer. It is helpful to note the property you have used to arrive at your answer & to include such equation before inserting numerical values. Remember to include units & to mind your significant figures! You may find it helpful to draw a diagram even if is not required. 1. A uniform magnetic field B is directed at an angle @ to the normal of a pentagonal loop with edges of unit length. a) What is the equation that describes the magnetic flux through the pentagonal loop? b) What are the SI units of each variable in this situation? Of the magnetic flux itself? c) Draw a diagram to describe this situation. d) Calculate the magnetic flux if the edges are 1.00 cm in length, the uniform magnetic field has a strength of 543.21 Gauss, and the angle is 75.00. 2. Write the equation for Faraday's Law & define it in your own words. 3. Consider the situation of problem 1. Calculate the emf induced in the pentagonal loop if the angle 8 is changing at a rate of 6.25 x 10-2 rad/s. 4. Consider again the situation of problem 1. If the uniform magnetic field is directed into the page, over some finite area, what is the direction of the induced current in the pentagonal loop if the pentagonal loop is dragged from left to right along the page into magnetic field? Sketch this situation & explain your answer using Lenz's Law
