Paramagnetic vs Diamagnetic Substances Magnetic Mystery

The video explains how electrons revolving around a nucleus generate a magnetic field, behaving like a magnet with a specific magnetic momentum known as Bohr magneton. It classifies materials based on their magnetic properties into paramagnetic, diamagnetic, ferromagnetic, antiferromagnetic, and ferrimagnetic substances. Paramagnetic substances, like chromium, have unpaired electrons and are weakly attracted by magnetic fields. Diamagnetic substances, such as zinc, have paired electrons and are weakly repelled by magnetic fields.

Describe the role of unpaired electrons in determining the magnetic properties of a substance.

How does the electronic configuration of zinc contribute to its classification as a diamagnetic substance?
