Problem

Three materials have the volume magnetic susceptibilities listed below: • Material P: χ=−1.0×10−5\chi = -1.0 \times 10^{-5} • Material Q: χ=+8.0×10−5\chi = +8.0 \times 10^{-5} • Material R: χ=+1.5×10−3\chi = +1.5 \times 10^{-3} Assuming each sample is placed in the same uniform external magnetic field, which sequence correctly orders the materials from weakest to strongest induced magnetization? a) Q,  R,  PQ,\; R,\; P b) P,  Q,  RP,\; Q,\; R c) P,  R,  QP,\; R,\; Q d) R,  Q,  PR,\; Q,\; P
