Symetries properties of electric and magnetic fields

Attention

  • Electric field  :

    • Let be a symmetric plane for the charge distribution.

      If  :

    • Let be an anti-symmetric plane for the charge distribution.

      If  :

    • Let be a symmetric plane for the charge distribution passing through point M, where we want to determine the electric field. Then :

    • Let be an anti - symmetric plane for the charge distribution passing through point M, where we want to determine the electric field. Then :

  • Magnetic field :

    • Let be a symmetric plane for the current distribution.

      If  :

    • Let be an anti-symmetric plane for the current distribution.

      If  :

    • Let be a symmetric plane for the current distribution passing through point M, where we want to determine the magnetic field. Then :

    • Let be an anti - symmetric plane for the current distribution passing through point M, where we want to determine the magnetic field. Then :
