Magnetic Properties of Matter: Practice Problem & Solution

23. The magnetic moment of a diamagnetic atom is: (2010 Mains)
Much greater than one
$1$
Between zero and one
Equal to zero

Solution Explained:

To solve this problem, we apply the core principles of Magnetic Properties of Matter. Understanding the underlying formula is key to arriving at the correct answer below:

In diamagnetic materials, electrons occur in pairs with opposite spins and their orbital motions cancel each other out. Thus, their individual magnetic moments cancel, resulting in a net magnetic moment equal to zero for the atom.
