Suppose a current-carrying circular loop is substituted with its equivalent magnetic dipole. A point situated on the loop lies in the

Step-by-step solution

A current-carrying circular loop behaves as a magnetic dipole with its magnetic moment vector perpendicular to the plane of the loop. The equivalent magnetic dipole is considered to be placed at the center of the loop, with its axis aligned along the normal to the plane of the loop. The broadside-on position (equatorial position) of a magnetic dipole is the plane perpendicular to its axis and passing through its center. This plane coincides exactly with the plane of the circular loop. Therefore, any point situated
