Question

The factor \((\frac {eh}{4\pi m_e})\) is the least value of the magnetic moment. This natural unit of magnetic moment is called Planck’s constant.

(a) True

(b) False

This question was addressed to me by my college director while I was bunking the class.

Answer 1

Correct option is (b) False

Explanation: The factor \((\frac {eh}{4\pi m_e})\) is the least value of the magnetic moment. This natural unit of magnetic moment is called Bohr magneton. The value of Bohr magneton is 9.27 × 10^-24 Am^2. So, that makes the above statement false.
