Question

Write the formula to calculate spin-only magnetic moment.

Answer 1

Spin only magnetic moment:

• When electrons move around freely, they create a magnetic field; this magnetic field created by electron motion is known as the magnetic moment.
• A spin-only magnetic moment occurs when an electron rotates on its own axis and generates a magnetic field.

The formula for the calculation of spin only magnetic moment

• ${\mu }_s=\sqrt{n(n+2)}$
• Here, $n$ is the number of unpaired electrons.
• The unit for a spin-only magnetic moment is the Bohr magneton (BM).
