What are Electromagnets?
Electromagnets are magnets that use electric current to generate magnetic fields. Unlike permanent magnets, which produce a steady magnetic field, electromagnets may be turned on and off by regulating the flow of electricity through a wire coil. They are commonly utilized in applications that demand changeable and regulated magnetic fields. A coil of wire twisted around a magnetic core, usually made of iron or steel, is what makes up an electromagnet. When electric current travels through a wire coil, it produces a magnetic field surrounding it in accordance with Ampère’s law.
Solenoid
A solenoid is an electromagnetic device made out of a coil of wire wound around a cylindrical or elongated core, usually comprised of ferromagnetic material like iron or steel. When an electric current flows through a wire coil, it generates a magnetic field surrounding it, which can exert force on objects in the field or cause mechanical motion. In this article, we will learn in detail about solenoid, its working and application.
