4 6 68% 4. Faraday's and Lenz's Law Field Day (these three problems are independent of each other) a. A long straight wire is oriented in the vertical direction and in the plane of the page. A loop of wire is in the plane of the page. The wire is brought closer to the loop. The induced current in the loop is counterclockwise as seen looking at the page. Indicate the direction that the current in the straight wire is flowing. b. A long straight wire is oriented in the vertical direction and in the plane of the page, the current in the wire is going in the down direction. A loop of wire is in the plane of the page. The loop is being moved. The induced current in the wire is in the clockwise direction as seen looking at the page. Draw a picture indicating all of this (you can use the above diagram as a guide), AND indicate the direction that the loop is being moved. C.|A long straight wire with I-3 A (in the up direction) is brought from x-6 cm to x-3 cm away from the center of a loop of wire in a time period of t=0 12 seconds. What is the induced current (just the magnitude) in the loop of wire is if has a radius of re0.5 cm and a resistance of R 25 OF Assume the strength of the magnetic field throughout the loop of wire is the same as at the center of the loop of wire
