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 :
