Statement-I : The magnetic field lines do not intersect.Statement-II: The direction of magnetic field at a point is unique

Statement-I: The magnetic field lines do not intersect. This is true because if they did intersect, it would imply that at the point of intersection, the magnetic field has more than one direction, which is not possible.

Statement-II: The direction of the magnetic field at a point is unique. This is also true and it is directly related to the first statement. At any given point in a magnetic field, the magnetic field has a unique direction. This is represented by the direction of the magnetic field line passing through that point.

Therefore, both statements are correct and they are related to each other. The uniqueness of the direction of the magnetic field at a point (Statement-II) is the reason why magnetic field lines do not intersect (Statement-I).
