if magnetic field lines can pass through a conductor then why dont they pass through soft iron ring is it bcoz of its material or bcoz of its shape a B lines can pass through a conductor However when a soft iron ring is placed in magnetic field no lines pass through the space inside the ring This phenomenon is called magnetic screening or Shielding and is used to protect costly wrist watches and other sensitive instruments from external magnetic fields Also know that the B field inside superconductors is always zero if kept in external B field This effect is known as Meissner Effect
