What is solenoid: The purpose of solenoid

The purpose of solenoid is to generate a magnetic field, so studying it is very important to understand how magnetic field are distributed around a current carrying solenoid . A solenoid is a type of electromagnet that generates a controlled magnetic field with a helical coil of wire. Learn how the magnetic field inside and outside a solenoid depends on its length, diameter, current and permeability, and how solenoids are used in various devices. A solenoid is a kind of electromagnet created using a helical wire whose length is much larger than its diameter, which produces controlled magnetic fields. The coil can generate uniform magnetic fields in space when an electric current is flowing through it. Solenoids are coils of wire that generate magnetic fields and move metal cores when electric current passes through them. Learn how solenoids work, what types exist, and how they are used in various fields such as automotive, industrial, and consumer electronics.
