Factors Affecting the Strength of Electromagnet
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field.
You have just made a magnet by using electricity. When you disconnected one end of the wire from the battery, the current did not flow anymore. The nail could no longer attract the pins. Its magnetic force was gone. An electromagnet can have magnetic force only when electric current is flowing through it.
