Moving Charges and Magnetism

Question:

In an atom, an electron with charge ' $e$ ' and mass $\mathrm{m}$ is revolving around the nucleus in a specific orbit with angular momentum $(\vec{L})$ and the equivalent magnetic dipole moment $(\mu)$ of that atom is : $\vec{\mu}=-\frac{e}{2 m} \vec{L}$, where $\frac{e}{2 m}$ will be:

Options:

Bohr's Magneton

Gyromagnetic Ratio

Specific charge of electron

Orbital Magnetic moment

Correct Answer:

Gyromagnetic Ratio

Explanation:
Gyromagnetic ratio of a particle or system can be defined as the ratio of its magnetic moment and angular momentum.
