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.

Required Answer :
Solenoid is a closely bound cylindrical coil of insulated metallic wire. A current carrying freely suspended solenoid behave like a magnet and when suspended freely, it rest in north-south direction.
A current carrying solenoid behave like a bar magnet with fixed polarities at its ends. The end of the current carrying solenoid at which the current flows anticlockwise behaves as a north pole while that end at which the direction of current is clockwise behaves as a South pole. The direction of magnetic field is always perpendicular to the direction of current flow and the magnitude of the magnetic field lines inside the solenoid is directly proportional to the current flowing through the solenoid.
Thus, when the current through the solenoid is reversed, the direction of magnetic field is also reversed.
Answer:
No, current carrying solenoid fall freely stay in North - South direction because it behaves as a bar magnet. When current flow through a solenoid is reversed the it direction is also reversed
