Question

there is either a convergence or divergence of magnanti field lines ner the ends of a current carrying straight solenoid . why?​

Answer 1

$\huge\bold\red{ANSWER}$

The divergence (degree of closeness) of magnetic field lines near the ends of a current carrying straight solenoid indicates a decrease in the strength of the magnetic field near the ends of the solenoid. ... So, a freely suspended current-carrying solenoid also aligns itself in the north-south direction.
