Susceptibility of a paramagnetic substance is

Step-by-step solution

The magnetic susceptibility is defined as = M/H , where M is magnetization and H is magnetic field strength. Paramagnetic materials exhibit atomic magnetic dipoles that align with an applied magnetic field, resulting in magnetization M parallel to H . Since both quantities share the same direction, > 0 . This alignment is partial and produces weak magnetization, making small in magnitude. Option analysis: A) Negative and large – incorrect, characteristic of diamagnetism B) Negative and small – incorrect, diamagneti
