Electro Magnets are the controllable type of magnet used. It may be possible but not practical to use rare earth magnets.

What are the physical properties of a magnet?
Magnetism is a physical property because attracting something to a magnet does not change the substance (change of the composition) itself and doesn't involve chemical reactions. The magnetic state of a material depends on temperature (and other variables, such as pressure and the applied magnetic field), so a material may exhibit more than one form of magnetism depending on its temperature, etc. However, the magnetism doesn't change the substance itself.
When rocks from cooling lava harden do they have the same magnetism as Earth's magnetism?
No, because Earth's magnetism "flips" about every half million years. When rock form from the cooling lava of volcanoes, the particular magnetic pattern at the time is "frozen" into the rocks. This was evidence that the alternating pattern of the rock has been slowly spreading out as the new crust is formed.
Why material has magnetic property?
The ability of some materials to become STRONGLY magnetized is related to the fact that the materials form magnetic domains, in which many atoms are aligned in a particular direction. Note that in this case, each atom is a tiny magnet.
What form of energy is moving electrical charges?
magnetism. Moving electricity generates magnetism
A force that attracts objects made of steel?
Magnetic Energy. Magnetic object is mostly every metal except copper which means that iron is magnetic when two iron objects are rubbed together they turn magnetic.
What mineral is a magnet?
Lodestone, a variety of the mineral magnetite, displays strong magnetism. Some other minerals are weakly magnetic, or display magnetism when heated.
The piece of metal is magnetic is that physical property or chemical property?
Magnetism is a physical property that is mediated by magnetic fields.The magnetic state of a material depends on temperature (and other variables, such as pressure and the applied magnetic field), so a material may exhibit more than one form of magnetism depending on its temperature, etc. However, a material's magnetism doesn't change the composition, and doesn't involve a chemical reaction.
Does photons have magnetism?
Photons form elecromagnetic waves, it's well known that electomagnetic waves have both electric and magnetic components (there are connected H~[n, E]).Thus photones can "have" magnetism.
Is magnetism a chemical or physical property?
It is a physical property >.<
How are electric currents and magnetism related?
Magnetism could be produced due to the flow of electrical current. This was first discovered by Oersted. By changing the magnetic flux linked with a coil electric current could be induced. This was first studied by Michael Faraday. Just due to the orbital motion or spin motion of electron magnetism is produced in tiny form and is known as magnetic dipoles. Such dipoles getting oriented in different form lead to form dia, para and ferro magnetic materials.
How is energy relate to magnetic?
I think what you mean to ask is, how do electricity and magnetism relate. well, electricity and magnetism combine in our universe to form what is known as electromagnetism, which the force that surrounds our Earth in deflecting solar radiation!

Can magnetism conducted like electricity?
for a short distances the magnetism can be well, said to be conducted in a magnetic material. For example if you have seen a transformer core then you will realize that the magnetic fluxes are being conducted across the core form primary winding to secondary winding. but if your question is if the magnetism can be conducted to larger distances like electricity then it might be theoretically possible but practically unrealizable due to huge losses and well earth's magnetism effects.
Is the force of magnetism stopped by any materials?
they redirect the magnetic field. for instance, a material known as mu-metal attracts all of the magnetism to it, thus redirecting the magnetic field away form other stuff. kinda like a faraday shield redirects electrons, mumetal redirects magnetism. the basic principal here is that some materials "want" magnetism more than others. thus you can put the magnet near it, and it will "hog" all of the magnetism. hope that's scientific enough :)
What does gauss law of magnetism say?
It states that the magnetic field B has divergence equal to zero.Source:Book: Electromagnetism Theory: A modern perspectiveAuthors: John and Bartlett p.134
How solidified magma comes to be magnetic?
As magma solidifies to form rock, iron-rich minerals in the magma align with Earth's magnetic field in the same way that a compass needle does. When the rock hardens, the magnetic orientation of the minerals becomes permanent. This residual magnetism of rock is called paleomagnetism.
