  1. PHY 2049: Physics II • Tutoring Center is open in room NPB 1215, M-F 12:00AM -4:00PM. It is free. • All homework assignments are now available online. • My office hours: MTW 3-4 PM

  2. HITT (read carefully) • Two 110-V light bulbs, one “25W" and the other “100W", are connected in series to a 110V source. Then: • A. the current in the 100-W bulb is greater than that in the 25-W bulb • B. the current in the 100-W bulb is less than that in the 25-W bulb • C. both bulbs will light with equal brightness • D. each bulb will have a potential difference of 55V • E. none of the above

  3. Magnet has two poles. N points to North • B Direction from N-S. • Brought to Medit. by Marco Polo. Maritime traffic across jumped.

  4. What direction are the forces in the picture above?

  5. ilB = mg  B = mg/il

  6. Crossed Fields • F = q[E+vxB] • For v = vo = E/B, goes straight. • For v > vo , goes up E B v

  7. Vy = Ey d, eEy = evx Bz Ex = ρ Jx Ey = Rh Jx Rh = B/ne x y Hall Effect

  8. Vy = Ey d, eEy = evx Bz Ex = ρ Jx Ey = Rh Jx Rh = B/ne x y Hall Effect

  9. Vy = Ey d, eEy = evx Bz Ex = ρ Jx Ey = Rh Jx Rh = B/ne x y Hall Effect Rh B Quantum Hall Effect

  10. F = ilB = i x B l

  11. Τ = M x B, M = NiA U = M.B

  12. Galvanometer

  13. Mg sinθr = μB sinθ μ = 2rLNi
