PYQ - Current in a solenoid — task. Physics CBSE Live product, Class 10.

In a long straight solenoid carrying current, North and South poles form at its ends. Which of the following statements is incorrect?

The straight, evenly spaced magnetic field lines within a solenoid indicate that the magnetic field inside is uniform at every point.
The strong magnetic field produced inside the solenoid can magnetize the soft iron placed inside it.
The pattern of the magnetic field associated with a current carrying solenoid is different from the pattern of the magnetic field around a bar magnet.
The N and S poles exchange positions when the direction of current through the solenoid is reversed.
