Question

What is meant by solenoid? How does a current carrying solenoid behave? Give it main cause

Answer 1

A solenoid is a conducting wire wound around an insulating material. A current carrying solenoid induces a magnetic field around it.A solenoid has a large number of close, insulated circular turns. The magnet at the centre of current carrying circular wire is along the axis; so when current is passed in a solenoid, the magnetic fields due to all circular turns are added and hence the field line becomes just as for a bar magnet. Solenoids are most commonly used as electromagnets.
