Describe and illustrate the magnetic field lines produced by a current-carrying circular loop.
(N/A) $1$. When a current $I$ flows through a circular loop,it generates a magnetic field around it.
$2$. Near the wire of the loop,the magnetic field lines are nearly circular and concentric,with their centers lying on the wire.
$3$. As we move towards the center of the loop,the magnetic field lines become straighter and more parallel.
$4$. At the exact center of the loop,the magnetic field lines are perpendicular to the plane of the loop.
$5$. The direction of the magnetic field can be determined using the Right-Hand Thumb Rule: if you curl the fingers of your right hand in the direction of the current,your thumb points in the direction of the magnetic field lines.
