Answer 2

$\large\boxed{\fcolorbox{blue}{yellow}{Answer:-}}$

Properties of magnetic

field lines or force :

(1) Magnetic field lines form closed loops magnetic dipole is conjectured to be analogous to an electric dipole but, unlike electric charges magnetic poles or charges are fictitious and conjectured. Since isolated magnetic poles are not observed, magnetic field lines do not originate or terminate at a point

(2) The tangent to a magnetic field line at a point gives the direction of the net magnetic induction B at that point.

(3) At a point in a magnetic field, the magnetic flux per unit area across an infinitesimal surface, containing the point and at right angles to the magnetic field lines, gives the magnitude of the magnetic induction at that point.

(4) Magnetic field lines do not intersect, otherwise the direction of the magnetic field at a point would not be unique.
