Solution

The correct option is A parallel straight lines.
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.

Q. Question 4
For a current in a long straight solenoid N- and S-poles are created at the two ends. Among the following statements, the incorrect statement is

(a) The field lines inside the solenoid are in the form of straight lines which indicates that the magnetic field is the same at all points inside the solenoid
(b) The strong magnetic field produced inside the solenoid can be used to magnetise a piece of magnetic material like soft iron, when placed inside the coil
(c) The pattern of the magnetic field associated with the solenoid is different from the pattern of the magnetic field around a bar magnet
(d) The N- and S-poles exchange position when the direction of current through the solenoid is reversed

Q. Assertion: Magnetic field inside a solenoid is in straight lines but while coming out of a solenoid, they diverge and move far apart.

Reason: The magnetic field is maximum inside a solenoid and starts to decrease as we move away from the solenoid.

Q. In which form the field lines inside the infinite solenoid are present ?
