Solenoids: Working Principle,
When an electric current is applied to a solenoid, it creates a powerful magnetic field that attracts or repels a magnetic material, ie magnetic plunger, to move inside of its housing. As the plunger moves back and forth, it creates the mechanical motion that powers the intended component. Solenoid magnets have an advanta…
