Superconductors?????? Wow

Some of you confuse about superconductors??? Do you know that ,with superconductors the equipments of electrical appliance no need batery or power source .

Kebanyakan logam tidak menunjukkan ciri ini. If a current flows in superconductors , the current still flows eventhough without power source.
