Example Formula

The Bohr magneton (µB) is a physical constant and the natural unit for expressing the magnetic moment of an electron caused by its intrinsic properties of spin and orbital angular momentum. The formula for the Bohr magneton is:

µB = eħ / 2me


  1. µB: Bohr magneton
  2. e: electronic charge
  3. ħ: reduced Planck's constant, equal to Planck's constant (h) divided by 2π
  4. me: mass of an electron

Who wrote/refined the formula

The concept of magnetic moment and Bohr magneton was developed by Niels Bohr, a Danish physicist, in 1913. This formula is primarily relevant in the field of quantum physics, specifically atomic physics and quantum chemistry, where it helps in understanding the magnetic properties of atoms and molecules.

Real Life Application

In real-life applications, the Bohr magneton plays a crucial role in magnetic resonance imaging (MRI) technology. MRI uses a strong magnetic field and radio waves to create detailed images of the body's organs and tissues. The understanding of magnetic moment and the Bohr magneton is essential for optimizing the performance of these medical imaging devices.

Key individuals in the discipline

Niels Bohr (1885-1962) is undoubtedly a key figure in this discipline. Bohr's contributions to the understanding of atomic structure and quantum theory won him the Nobel Prize in Physics in 1922. Another important individual is Wolfgang Pauli, who introduced the concept of spin quantum number, which is crucial for the understanding of the Bohr magneton.
