Question

What us meant by solienoid ?how does a current carrying solenoid bhave?give its main use

Answer 1

A solenoid is a type of electromagnet when the purpose is to generate a controlled magnetic field. If the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
behavior:
Magnetic field lines are produced around the solenoid when a current is allowed to flow through it. The magnetic field produced by it is similar to the magnetic field of a bar magnet. ... Hence, one end of the solenoid behaves as a north pole and the other end behaves as a south pole

Answer 2

SOLENOID: A solenoid is a coil of insulated or enameled wire wound on a rode shaped form made of solid iron, solid steel, or powdered iron. Devices of this kind can be used as electromagnets, as inductors in electronic circuits, and as miniature wireless receiving antennas.

HOW IT BEHAVES: Magnetic field lines are produced around the solenoid when a current is allowed to flow through it. The magnetic field produced by it is similar to the magnetic field of a bar magnet. Hence, one end of the solenoid behaves as a north pole and the other end behaves as a south pole.

USES: Electromagnetic solenoids find uses all over the world. They're in hotel door locks, water-pressure valves in air conditioning systems, MRI machines, hard disk drives, speakers, microphones, power plants, and cars. You can hardly swing a bat without hitting a solenoid.

Speakers and microphones, for example, both contain solenoids.
