Can a freely suspended current carrying solenoid stay in any direction? Justify your answer. What will happen when the direction of current in the solenoid is reversed? Explain.
A current carrying solenoid behaves like a magnet.
So, when it is suspended freely it will align itself in the north-south direction.
On reversing the current through the solenoid, the north and south poles will get exchanged and the solenoid will turn 180 ° .
