Question

what happens when a freely suspended current carrying solenoid is brought near iron fillings​

Answer 1

Answer:

The direction of magnetic field is always perpendicular to the direction of current flow and the magnitude of the magnetic field inside a 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 reversed.

Answer 2

Answer:

Explanation:

A current-carrying solenoid behaves like a bar magnet. We know that a  bar magnet attracts iron objects . So, a freely suspended current-carrying solenoid also attracts iron objects. when current is not passed the solenoid loses its property of a magnet.
