What is solenoid:

What is Solenoid ?A solenoid is a long, insulated copper wire closely wound on a hollow cylindrical glass or plastic tube in the form of a helix. A solenoid works on electromagnetism and electromagnetic force. It consists of a round cylindrical coil that has wire turns and a metal rod.. A solenoid is a copper wire with a resistive coating coiled into a chain of loops. When an electric current flows through a solenoid , magnetic lines of force form in a pattern. Solenoid magnetic fields are similar to those created by bar magnets. A solenoid 's open ends function as magnetic north and south poles, respectively. What is a Solenoid? A solenoid is a simple electrical component set up in a spiral-wired arrangement . It is defined as an electrical device consisting of coils of wires covered around a soft iron and movable core which we use as an electromagnet.
