A steady current I flows along an infinitely long hollow cylindrical conductor of radius R. This cylinder is
placed coaxially inside an infinite solenoid of radius 2R. The solenoid has n turns per unit length and
carries a steady current I. Consider a point P at a distance r from the common axis. The correct statement(s)
is (are)
  • a)
    In the region 0 < r < R, the magnetic field is non-zero
  • b)
    In the region R < r < 2R, the magnetic field is along the common axis
  • c)
    In the region R < r < 2R, the magnetic field is tangential to the circle of radius r, centered on the axis
  • d)
    In the region r > 2R, the magnetic field is non-zero
Correct answer is option 'A,D'. Can you explain this answer?

A steady current I flows along an infinitely long hollow cylindrical c...

Explanation:

Region 0 < r="" />< />
- In this region, the magnetic field due to the current flowing through the infinitely long hollow cylindrical conductor is non-zero.
- This is because the current flowing through the conductor produces a magnetic field around it.

Region R < r="" />< />
- In this region, the magnetic field is along the common axis.
- The magnetic field due to the solenoid dominates in this region, and it is along the axis of the solenoid.

Region R < r="" />< />
- In this region, the magnetic field is tangential to the circle of radius r, centered on the axis.
- This is because the magnetic field due to the solenoid is tangential to the circles of radius r around the axis.

Region r > 2R:
- In this region, the magnetic field is non-zero.
- Both the solenoid and the current carrying cylinder contribute to the magnetic field in this region, leading to a non-zero magnetic field.

Therefore, the correct statements are A and D.
