Maxwell’s Equations: Free Space, No Charges Current J and charge ρ are zero Integral form of Maxwell equations in free space: 0 = S S d B G G G G no magnetic ‘charges’ B d G G G G 0 = S S d E no electric charges changing magnetic field = A C S d dt l d E E G G G G creates curly electric field changing electric field = A C S d t l d B 0 0 ε μ There is remarkable symmetry between electric and magnetic fields! creates curly magnetic field
