For a current in a long straight solenoid N-pole and S-poIe 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-pole and S-pole exchange position when the direction of current through the solenoid is reversed.
Correct answer is option 'C'. Can you explain this answer?

A solenoid behaves like a bar magnet. Hence the pattern of magnetic field associated with solenoid and around the bar magnet is same.

The only difference is, solenoid have no fixed direction of magnetic field where as bar magnet have.
so it may be the direction of both would be in opposite directions for each other.

The incorrect statement is option 'C': The pattern of the magnetic field associated with the solenoid is different from the pattern of the magnetic field around a bar magnet.

Explanation:
Let's analyze each statement to understand why option 'C' is incorrect.

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.
- This statement is correct. Inside a long straight solenoid, the magnetic field lines are parallel and equidistant, forming straight lines. This 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 magnetize a piece of magnetic material like soft iron when placed inside the coil.
- This statement is correct. The magnetic field produced by a solenoid is strong and uniform inside. When a magnetic material like soft iron is placed inside the solenoid, it gets magnetized due to the influence of the strong magnetic field.

c) The pattern of the magnetic field associated with the solenoid is different from the pattern of the magnetic field around a bar magnet.
- This statement is incorrect. The pattern of the magnetic field associated with a solenoid is similar to the pattern of the magnetic field around a bar magnet. Both have a north pole at one end and a south pole at the other end. The magnetic field lines around a bar magnet and inside a solenoid follow a similar pattern.

d) The N-pole and S-pole exchange position when the direction of current through the solenoid is reversed.
- This statement is correct. When the direction of current through the solenoid is reversed, the north pole and south pole of the solenoid also get reversed. The N-pole becomes the S-pole, and vice versa.

In conclusion, the incorrect statement is option 'C' because the pattern of the magnetic field associated with the solenoid is not different from the pattern of the magnetic field around a bar magnet.
