PHYS 220 — Homework #8

For this homework assignment, you'll need the results of Lab #8. This homework is due Wednesday, 2 April.


  1. Explain the discrepancies between your results and the theoretical values for B in the middle and at the ends of the solenoid for the various N & h parameters in #2 of Lab #8.
  2. For an ideal, long solenoid, the B-field inside is uniform and zero outside. Explain the results depicted in the top panel of my visualization script.
  3. In lines #60–#64 of my visualization script, the B-field is set to zero if the point lies within 5 units of the origin. This was done for strictly for visualization purposes. Explain.
  4. Does the B-field depicted in the bottom panel of my visualization script make sense physically? Explain.
  5. Describe an exceedingly simply physical system that would give results qualitatively similar to those depicted in the bottom panel.
  6. Explain the asymmetry in the bottom panel of my visualization script.
