Difference between Solenoid and Bar Magnet
Here are the differences between a solenoid and a bar magnet.
Solenoid | Bar Magnet |
|---|---|
Solenoid is electromagnetic i.e. it’s magnetic effect is created due to flow of current. | Bar magnet is permanent magnet, which is naturally magnetic. |
Poles can be reversed depending on the direction of flow of current. | Bar Magnet has fixed poles. |
Solenoid is made using soft iron or steel. | Bar magnet are formed from hard steel or iron. |
Strength of magnetic field depends on the flow and quantity of current. | Strength of magnetic field depends on the material used to create the magnet. |
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.
