How is Faraday’s /Lenz law consistent with the magnetic force on a moving charge? An example may help. That is, find an example where Faraday’s/Lenz laws predict the same direction of current as the magnetic force equation. In question 200 we were asked to find three fundamental ways in which we predicted we could induce an Emf using Faraday’s Law. We will now explore examples of them. A 3.5 T field faces the same way as a 20.0 Ù loop...

7. Using the Biot-Savart-Law, determine the magnetic field at point C due the current loop seen in the figure below, where the two arcs are segments of two circles with radii Ri and R2 respectively, and with their centers located at C. The current, I, circulates through the loop in counter-clockwise direction. Your expression should depend only on the two radii, the current and the angle θ
