Assignment: Magnetic Fields Now that you've had some practice, apply the feedback from your teacher to complete this assignment. In this assignment, demonstrate your understanding of magnetic fields by completing a problem set. Instructions Your task is to complete the questions in the problem set. Read each question carefully, identifying your given values. Show all formulas and calculations used to solve the problems. Report your answers to the correct number of significant digits and with the correct units. Questions 1. To facilitate traffic flow, many stoplights now have a sensing system based on inductance to determine if a car is waiting at a red light. If that is the case, the light is then switched to green. Using credible sources, write a paragraph explaining how the system works. Include any in-text citations along with a reference list in APA style. (10 marks) 2. A 3. 00 m long straight copper wire has a current of 9. 0 A in it as it passes through a magnetic field. The magnitude of the force on the conductor is 2. 00 N. The angle between the current and the magnetic field is 60. 0 . What is the magnitude of the uniform magnetic field
