How is the single-sided magnet?

　　Artificial magnet is divided into hoofed magnet and bar magnet, which is the most common in our daily life. The hoofed magnet is more popular.

　　Single-sided magnet, offered by magnetic products factory, refers to a magnetic, whose one side has magnet and the other side’s magnet is weak. Method is to use special processing galvanized iron sheet to wrap one side of double-sided magnet. The wrapped side of magnet will be blocked. Magnetic force is reflected to the other side, and the magnetic property on the other side will be enhanced.

　　On some occasions, only one side needs magnetic property. If the other side is magnetic, it will cause damage or disturbance. In some fields, such as packing box, it only needs that one side is magnetic. On the other side, the magnetic is of no use. This use of single-sided magnetic will greatly reduce the cost and save the magnetic material.
