Question

compare the pattern of the field produced in case of a current carrying solenoid with the magnetic field of a bar magnet

Answer 1

both r same
1 emerges from north merges to south in both cases
(see arrows)
2 closed continuous curves

hope it helps
please mark it as brainliest✌✌

Answer 2

here mate,, here is ur ans..

• the nature of magnetic field lines produced by a solenoid is similar to that of a bar magnet.

• the field lines are closed curves, they emerge from the north pole  and merge in the south pole outside the magnet and inside the direction is from south to north.

• inside the solenoid and a bar magnet the field is uniform.

• the poles in a solenoid can be determined by using a bar magnet or by clock face rule.
