📊Student Analytics & Stats
Total Attempts: 6
Accuracy Rate: 16.7%
Step-by-Step Solution
For a perfect diamagnetic substance, the magnetic susceptibility is $\chi = -1$. This is because diamagnetic materials completely expel magnetic field lines from their interior, making the relative permeability $\mu_r = 0$, and since $\chi = \mu_r - 1$, it results in $-1$.
