A magnetic keeper is a strip of soft iron or steel which is placed across the poles of a permanent magnet to help preserve the magnetism.

The idiom "finder's keepers" actually refers to a Roman law. The law basically meant that once something was unowned or abandoned, whoever found it could keep it.

the magnetic keepers are made up of insulators. generally wood
Magnetic keepers can be thought of as materials that complete the magnetic circuit of the magnet. They do this by providing a paramagnetic link from one pole of the magnet to the other. That way the magnet can resist the effects of other magnetic fields that might tend to depolarize or demagnetize it.

Mineral present in molten magma.
A region in which the magnetic fields of atoms, or electron spin, are grouped together and similarly aligned.
Magnetic flux is the product of the average magnetic field times the perpendicular area that it penetrates. -jkharris information found on: http://hyperphysics.phy-astr.gsu.edu/Hbase/magnetic/fluxmg.html
when magnets are kept loose their magnetic power becomes weak. therefore a non magnetic substance should be kept in between of two magnets while storing them. so that there is no continuous attraction or repulsion between them.
A magnet is a material or object that produces a magnetic field.
A magnetic keeper, also known as a magnetic shunt or magnetic loop, is a piece of ferromagnetic material that is used to enhance and maintain the strength of a magnetic field. It is typically placed across the poles of a permanent magnet or an electromagnet to prevent the loss of magnetic strength when it is not in use or being used for a specific purpose. The magnetic keeper helps to redirect and concentrate the magnetic flux within the magnet, prolonging its effectiveness.
