Tin Men has been written and directed by Barry Levinson in a style similar to his inspired 1982 comedy, Diner.. That was a movie about a crowd of teenage buddies who were mystified by sex, life, ambition and especially women. They were trying to grow up at an age when they were already supposed to be grown up.
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.
An electromagnet is made from a coil of wire that acts as a magnet when an electric current passes through it but stops being a magnet when the current stops. Often, the coil is wrapped around a core of soft ferromagnetic material such as steel, which greatly enhances the magnetic field produced by the coil. The overall strength of a magnet is measured by its magnetic moment or, alternatively, the total magnetic flux it produces.
