Schwinger magnetic induction

In quantum electrodynamics (QED), the Schwinger magnetic induction is

${\displaystyle S_{mi}={\frac {m_{e}^{2}c^{2}}{q_{e}\hbar }}\simeq 4.41401\times 10^{9}\,\mathrm {tesla} ,}$

where m_e is the mass of the electron, c is the speed of light in vacuum, q_e is the elementary charge, and ħ is the reduced Planck constant.^[1]

${\displaystyle S_{mi}={\frac {E_{\mathrm {s} }}{c}}}$

where E_s is the Schwinger limit.
