" Why two magnetic field lines never cross each other? "

Why do the electric field lines never cross each other ?

Why don't two magnetic field lines intersect each other?

Why don't two magnetic field lines intersect each other?

Why can't two magnetic field lines cross each other? Draw the magnetic field lines (including field directions) of the magnetic field due to a long straight solenoid. What important property of this field is indicated by this field line pattern? Name any two factors on which the magnitude of the magnetic field due to this solenoid depends.
