Day 222: Covariant Formulation of Electromagnetism

Day 222 of 2,016~16 min read

Learning Objectives

  • •Construct the electromagnetic field tensor $F^{\mu\nu}$ from $\mathbf{E}$ and $\mathbf{B}$
  • •Write Maxwell's equations in covariant tensor form
  • •Define and use the electromagnetic 4-potential $A^{\mu}$
  • •Understand gauge transformations in relativistic notation
  • •Derive the Lorentz force from the field tensor
  • •Connect the covariant formulation to quantum electrodynamics
