[題目]

Which of the following statement(s) is(are) wrong?

    (a) Lorentz force law can be derived from Maxwell's equations.
    (b) If the magnetic monopole exists, it will be possible to violate the
        energy conservation law.
    (c) The electric field E exerts a force on a magnetic charge in the
        direction of its motion.
    (d) The fact that generators generate electric currents is an evidence of
        Faraday's law.
    (e) The flux rule ε = -dΦ/dt is invalid when the magnetic field is
        changing and the loop is moving at the same time.

我認為(c)錯誤，(d)、(e)正確，問題在a、b

a的話，記得靜磁的兩個Maxwell eg.是皆是由必歐．沙伐定律導出的，估計是錯誤，但不確定


b就幾乎沒頭緒了...


煩請版上高人解答

推 frankchiang:必歐.沙伐定律可以導出磁力，就可以導出勞倫茲力了
→ mantour:必歐沙伐定律只告訴你磁場並沒有告訴你磁場和受力的關係
→ chungweitw:a 是對的. 但是不是從BBiot-Savart law 出來的
→ chungweitw:然後. (e) 是錯的吧.
→ ed78617:嗯，又看了一次，e應該是錯誤...
