$A$ circular loop placed in a plane perpendicular to the plane of paper carries a current when the key is $ON$. The current as seen from points $A$ and $B$ (in the plane of paper and on the axis of the coil) is anti-clockwise and clockwise respectively. The magnetic field lines point from $B$ to $A$. The $N-$ pole of the resultant magnet is on the face close to

• A
  $A$ if the current is small, and $B$ if the current is large
• B
  $B$
• C
  $A$
• D
  $B$ if the current is small and $A$ if the current is large
