• Lagrangian density
• Maxwell's equations
• Constraint
• Variation

In 2008 Civelek and Bechteler obtained a Lagrangian density which can lead to all four Maxwell's equations by separately using two groups of constraints. In this communication, a new Lagrangian density is established, which can directly lead to all four Maxwell's equations by simply using one group of constraints.
