25. Now suppose a weak (in the sense that eB ≪ 2mω) magnetic field B⃗ = Bẑ is turned on normal to the plane of this orbit. The original angular frequency ω becomes ω' = ω + Δω. Suppose the orbital radius is unchanged. What is Δω? (A) eB/2m_e (B) √(eωB/(m_e r_B)) (C) evB/(m_e r_B) (D) v/r_B (E) none of the above.
24. What is the magnitude of magnetic (dipole) moment μ⃗ associated with this motion? (A) evr/2 (B) evr (C) evr² (D) eπr² (E) none of the above.
23. [23-25] As described in the Bohr model, an electron is circularly orbiting a proton in a hydrogen atom with radius r_B and velocity v. The orbital angular momentum of the electron is in the +ẑ direction. 'I' is the electron current. What is the magnitude of magnetic field at the center of the orbit due to the electron's motion? (A) μ₀I/(πr_B²) (B) μ₀I/(2πr_B) (C) μ₀I/(2r_B) (D) μ₀I/r_B (E) none of the above.

22. What are the two basic postulates through which Einstein based his Special Theory of Relativity on (10 points)?
21. A current I is running uniformly toward the positive z direction on a long thin plate lying on the x-z plane with wider width w. Find out the magnetic field at a place very close to the center part of the plate (3 points). If this plate is bent to form a cylinder centering at the z axis with radius r = w/2π, what will be the magnetic field inside and outside this cylinder (3 points)? What is the pressure acting on this cylinder due to the magnetic force induced by the parallel current (4 points)?
