Question

are the magnetic field line closed? explain

Answer 1

HLO MATE HERE IS UR ANSWER .

⭐. The magnetic field lines appear to be closed loop, but we canť conclude that lines are closed or open loops .

⭐. Because the alignment of lines that are passing the bar magnet should be considered.

⭐. If we observe the field lines by a solenoid, the feild lines out side the solenoid are continuou with those in side.

⭐. Out side the solenoid the direction of the field lines is from north to south while inside , the direction is from south to north . Thus the magnetic field lines are closed loops.
