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, all electrons are paired, and the magnetic moments of paired electrons cancel each other out completely in every atom. Hence, each diamagnetic atom has zero net magnetic dipole moment.
