Why steel becomes a permanent magnet after electric current is passed through it?
When an electric current passes through steel, it creates a magnetic field within the steel. This magnetic field aligns the magnetic domains in the steel, causing it to become a permanent magnet. The alignment of the magnetic domains allows the steel to retain its magnetism even after the electric current is removed.
