Using iron and/or steel in combination with a magnet can enhance the magnetic force. This creates what is known as a magnetic system.
The illustrations give an idea of how much stronger the magnetic system is than if the magnet in the magnetic system were used on its own. Of course, the right design is necessary for this to work.
Remember that magnetic systems are very sensitive to air gaps!
