One of the common methods for the magnetization of steel is the electrical method. This technique involves placing a steel bar within a coil of wire, known as a solenoid. When direct current (DC) flows through the coil, it generates a magnetic field that aligns the magnetic domains within the steel. This alignment results in a strong and effective magnetization, making it suitable for applications such as electromagnets and magnetic storage devices. The electrical method is favored for its efficiency and ability to produce strong magnetic fields quickly.

Another widely used technique for the magnetization of steel is the stroking method. In this process, a steel bar is stroked with a magnet, which induces magnetism by aligning the magnetic domains in the direction of the applied magnetic field. This method is simple and can be performed manually, making it accessible for smaller applications. However, the strength of the magnetization achieved through this method is generally weaker compared to the electrical method.

Hammering is yet another technique that can be employed for the magnetization of steel. When a steel bar is placed in the direction of a strong magnetic field and gently hammered, the impact helps align the magnetic domains within the steel. This method can be enhanced by slightly heating the steel before hammering, which allows for better alignment of the domains. While effective, the hammering method requires careful handling to avoid damaging the steel.
