Question

the magnetic field lines inside a solenoid are in the form of parallel atraight lines the reason for this is the mafnetic field inside the solenoid is ​

Answer 1

Answer:

1) Magnetic field of a solenoid carrying current is similar to bar magnet as it also has the poles on either side and field lines(magnetic) are curve outside and straight inside the solenoid

OR

2) A coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder is called a solenoid. The field lines inside the solenoid are in the form of parallel straight lines. This indicates that the magnetic field is the same at all points inside the solenoid.
