MCQ
What is incorrect for current carrying solenoid
  • A
    its pattern of field lines just like pattern of field lines of bar magnet
  • B
    it is used to produce uniform field
  • C
    its magnetic field does not depends on radius of cross section of frame
  • ✓
    when it is freely suspended it always stays perpendicular to magnetic meridian
✓

Answer

Correct option: D.
when it is freely suspended it always stays perpendicular to magnetic meridian
d
A solenoid is equivalent to a bar magnet which axis is along the field if it is freely suspended.
