MCQ
Consider the magnetic field produced by a finitely long current carrying wire.
  • A
    the lines of field will be concentric circles with centres on the wire.
  • B
    There can be two points in the same plane where magnetic fields are same.
  • C
    There can be large number of points where the magnetic field is same.
  • ✓
    All of the above
✓

Answer

Correct option: D.
All of the above
d
If we take plane parallel to the length of wire function the all prints one plane will be current Field will be inversely proportional to the $\perp$ distance from the wire
