Let us assume that the wire ring lies in the *xy*-plane. Therefore, the
vertical direction to the plane is along the *z*-axis. The magnetic field
at each infinitesimal length segment of the loop can be resolved into a
component in the z-direction and the other in the *xy*-plane. As the field
is radially divergent the component of the field in the *xy*-plane at each
point on the circumference of the loop will have the same magnitude
and it will be radially normal to the circumference at that location. The
contributions to the force on the current carrying circular loop due to
z-components of the magnetic field at opposite length pairs on the circumference
will cancel each other. Therefore, the force on the loop will be due to the
components of the magnetic field in the *xy*-plane and the total magnitude
of the force will be
. The
direction of the net force on the loop will be along the *z*-axis.
