An electromagnet is a kind of magnet whose magnetic field is created by the flow of electric current. The magnetic field disappears when the current stops. Electromagnets offer the advantages of controlled holding power and on command release. Through the application of controlled DC electrical current, electromagnets have the ability to attract and hold ferrous materials with varying degrees of force, and to release the item as required.
