1. Which of the following correctly describes the magnetic field near a long straight wire?

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

The pattern of the magnetic field associated with the solenoid is different from the pattern of the magnetic field around a bar magnet.
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
The strong magnetic field produced inside the solenoid can be used to magnetise a piece of a magnetic material like soft iron when placed inside the coil
The N and S-poles exchange position when the direction of the current through the solenoid is reversed
