  4. why do electric field lines of force always stay perpendicular to their surface , i mean why do they don't make any other angle with it ?
  5. we all know that according ti kirchoff's loop rule , the potential difference across a loop is zero then how emf induces in a close loop when a bar magnet is taken away or towards it ?
  6. but according to lorrenz force both electrostatic and magnetic force act on a moving charge particle so i think we cant say , magnetic field is moving electric field
  7. why do a moving charge particle create magnetic field which it does not produce in stationary phase , i mean what special thing come in it when it starts moving ?
