instead of sayi...i made some changes to this entry.<br />instead of saying electrostatic means no rate of change of electric field AND no magnetic field, i chose to say now that electrostatic CAN have magnetic field, as in the case of steady current.<br /><br />in the case of steady current, magnetic fields exist, but electrical charges are still in equilibrium and fields are staticshinlianghttps://www.blogger.com/profile/16547059348411669522noreply@blogger.com
