Solenoids are complex coils of wire that are used for the transfer of electricity into mechanical energy, or even for creating a uniform magnetic field. These coils have been around for years, used in a variety of applications, but in recent years, more research has been done on solenoids, expanding their use even further. Very simple in construction, these coils offer physicists and engineers the ability to create magnetism and turn electrical impulses into mechanical, or linear energy. While most might not know much about these special coils, they are in use in a variety of everyday mechanisms and have the potential for use in many more types of mechanical systems.
Solenoids are electrical current carrying coils of wire in the form of a cylinder that typically surrounds an iron core that has the ability to move within the coil. The iron core is what helps to convert electricity generated into mechanical energy for movement. The coils tend to be in the shape of a helix, cylindrical in nature. For physicists, a solenoid can be used as a means to generate an artificial electromagnetic field. When constructed slightly differently, the solenoid can help turn electricity into actual mechanical energy for motion. There are tons of everyday uses for solenoids. Most of us make use of these on a daily basis without ever knowing they are at work or even present.
