What happens to the magnetic field lines at the center of the circular loop formed by the bent wire?

At the center of a circular loop formed by a bent wire carrying current, the magnetic field lines align in a straight and perpendicular manner to the plane of the loop. This alignment occurs because the contributions of magnetic fields from individual segments of the loop add up constructively at the center. The circular symmetry of the loop results in the magnetic field lines forming a pattern that resembles straight lines passing through the center. This configuration highlights the magnetic field’s concentration and uniformity at the central point, a characteristic feature observed in situations where current flows through a closed loop.
