Answer the following questions related to the magnetic field produced by a current-carrying circular loop.
(i) Define magnetic field lines.
(ii) List any four factors on which the magnitude of the magnetic field at the centre of a circular current loop depends.
(iii) If the current in the loop is doubled while all other factors remain unchanged, what qualitative change will occur in the magnetic field at the centre? Give reason.
