CHAPTER 31: Maxwell’s Equations and Electromagnetic Waves Responses to Questions 1. The magnetic field will be clockwise in both cases. In the first case, the electric field is away from you and is increasing. The direction of the displacement current (proportional to E d dt Φ ) is therefore away from you and the corresponding magnetic field is clockwise. In the second case, the electric field is directed towards you and is decreasing; the displacement current is still away from you, and the magnetic field is still clockwise. 2. The displacement current is to the right. 3. The displacement current is spread out over a larger area than the conduction current. Thus, the displacement current produces a less intense field at any given point. 4. One possible reason the term 0 E d dt ε Φ can be called a “current” is because it has units of amperes. 5. The magnetic field vector will oscillate up and down, perpendicular to the direction of propagation and to the electric field vector.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
