Electromagnets
Magnets attract materials that are ferromagnetic, such as iron, nickel, and cobalt. These materials contain atoms with unpaired electrons that align their magnetic moments in response to an external magnetic field.
Permanent magnets are made from materials that retain their magnetic properties for a long time without the need for an external magnetic field. Examples include neodymium magnets and samarium-cobalt magnets. These materials have high coercivity, which allows them to maintain their magnetism over long periods.
Magnets are attracted to ferromagnetic metals such as iron, nickel, and cobalt. These metals contain magnetic domains that align with an external magnetic field, causing them to be attracted to a magnet.
North poles attract south poles, and the other way around as well. Two poles of the same kind will repel eachother.
Some stainless steel alloys can be slightly magnetic, allowing them to attract magnets. This is often due to the presence of certain elements like iron in the alloy composition. However, stainless steel as a whole is considered non-magnetic and the degree of magnetism can vary based on the specific type of stainless steel used.
The Maglev refers to a train that is vastly popular in the country of Japan. The train is powered by magnets and magnetic fields, as opposed to wheels and gasoline. These trains are capable of safely reaching speeds that traditional trains cannot.

Maglev trains are powered by electricity. They use electric power to propell themselves by creating a magnetic field between the track and the train, allowing it to levitate and move forward without direct contact with the track.
Non-magnetic metals such as copper, aluminum, and lead do not typically attract to magnets. These metals do not have magnetic properties like iron, nickel, and cobalt, which are attracted to magnets.
There are a variety of ways to levitate things. It can be done by magnetic repulsion (which is sometimes used to levitate entire trains), by hidden wires, by wind (airplanes fly by a kind of levitation - the word levitate simply means, to lift up) by the buoyancy of hydrogen or helium gas, etc. It cannot be done by telekinesis, however. That is science fiction.

The name is kind of self explanatory. Magnetic eyelashes are false eyelashes that connect to your lash line with magnets rather than glue. They stick by sandwiching your natural lashes between two sets of magnetized eyelashes.
the old trains
neither. they separate because of magnetic fields. its not kinetic. its not potential. If you hold them together.. the "push" of them trying to get apart is storing some potential energy.. kind of like a spring. I guess you'd call it elastic potential energy because i dont know if there is such a thing as magnetic potential energy... hmm..
not really. is depends on what kind of magnets they are.
