Question
A sample of the paramagnetic salt to which the magnetization curve of Fig. $32-17$ applies is held at room temperature ( $300 \mathrm{~K}$ ). At what applied magnetic field will the degree of magnetic saturation of the sample be (a) $50 \%$ and (b) $90 \%$ ?(c) Are these fields attainable in the laboratory?
Step 1
This is represented by the equation: \[ \frac{M}{M_{max}} = \frac{B}{kT} \] where $B$ is the applied magnetic field, $k$ is the Boltzmann constant, and $T$ is the temperature. Show more…
