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.
