Current in a solenoid — task. Physics CBSE Live product, Class 10 (2025-26).

Choose the correct answer:

For a long solenoid with current passing through it, N and S poles are produced at the ends. Pick the incorrect statement.

Inside a solenoid, the magnetic field lines run straight and parallel, showing that the field is uniform throughout its interior.
Because the solenoid produces a strong magnetic field, any soft iron placed inside gets magnetized.
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.
