Question
5. True/False In a magnetic circuit that includes an air gap, the total reluctance of the circuit is typically dominated by the reluctance of the high-permeability core material rather than the air gap itself. Explain: 6. A long conductor is oriented in the +z direction (out of the page). It is moving in the +x direction with a constant velocity u, through a magnetic field pointing in the -x direction, -Bux. Which of the following statements correctly describes the polarity of the induced EMF on this conductor? A. The positive charge will accumulate on the end of the conductor out of the page (+z). B. The positive charge will accumulate on the end of the conductor into the page (-z). C. No induced EMF will be present on the conductor in this case. D. None of these are correct.
