일반물리학 2 — Maxwell's Equations; Magnetism of Matter: Problem 19

19 Figure 32-21 shows a loop model (loop L) for a diamagnetic material. (a) Sketch the magnetic field lines within and about the material due to the bar magnet. What is the direction of (b) the loop’s net magnetic dipole moment \(\vec{\mu}\), (c) the conventional current \(i\) in the loop (clockwise or counterclockwise in the figure), and (d) the magnetic force on the loop?
