PHY 172, Writing Assignment 9 Due by 8 AM, June 3, 2024 Name: DePaul ID Number: You will directly type your answers in Gradescope. 1) (3 points) Pick one of the personas that we discussed on Thursday's class and write a few sentences about one obstacle of the personas that resonated with you and why. Full descriptions of the personas are on D2L, in the Writing Assignment folder. 2) (5 points) In this problem, we will consider a loop of wire where a uniform magnetic field B exists as shown. The resistance of the loop is R. For the : purposes of this problem, we will assume that the area vector & A" points out of the page. Initially, the field is perpendicular to the plane of the loop and is directed out of the page. The loop can rotate about either the vertical or horizontal axis, passing through the midpoints of the opposite sides, as shown. A. Which of the following changes would induce an electromotive force (emf) in the loop? Check all that apply. When you consider each option, assume that no other changes occur. 1. The magnitude of B increases. ii. The magnitude of B decreases. iii The loop rotates about the vertical axis (vertical dotted line) shown in the diagram. iv. The loop rotates about the horizontal axis (horizontal dotted line) shown in the diagram. v. The loop moves to the right while remaining in the plane of the page. vi. The loop moves toward you, out of the page, while remaining parallel to itself. Justify each of your choice(s). In your justification include the information shown in the figure and the relevant equation(s). B. Which of the changes would result in a clockwise emf in the loop? Check all that apply. When you consider each option, assume that no other changes occur. i. The magnitude of B increases. ii. The magnitude of B~ decreases. iii The loop rotates about the vertical axis (vertical dotted line) shown in the diagram. iv. The loop rotates about the horizontal axis (horizontal dotted line) shown in the diagram. Page 1 of 2
