Question What is meant by solenoid? How does a current carrying solenoid behave? Give its main use.Submitted on 22/2/2024 | Answered by Vandana Rana
Answer :
solenoid: A coil of many circular turns of insulated copper wire wound on a cylindrical insulating body (i.e., cardboard etc.) such that its length is greater than its diameter is called solenoid.When current is flowing through the solenoid, the magnetic field line pattern resembles exactly with those of a bar magnet with the fixed polarity, i.e. North and South pole at its ends and it acquires the directive and attractive properties similar to bar magnet. Hence, the current carrying solenoid behave as a bar magnet.
use ofcurrent carrying solenoid: It is used to form a temporary magnet called electromagnet as well as permanent magnet.
