Iron, nickel, cobalt and gadolinium are naturally ferromagnetic elements. Common usage of the term "magnetic" refers to this form of magnetism. Other elements are capable of forming magnetic compounds, but are not magnetic in their pure states.Know More
Powerful rare earth magnets are referred to by the names of their component rare earth elements, but these elements are not ferromagnetic on their own. Neodymium magnets are the best-known type of rare earth magnets and composed of an alloy of neodymium, iron and boron. Samarium magnets consist of an alloy of samarium and cobalt. These are useful at high temperatures where neodymium magnets would lose their ferromagnetism.
Other elements that are naturally nonmagnetic can undergo laboratory-induced ferromagnetism. When lithium gas is supercooled to near absolute zero, it exhibits ferromagnetism. This is the only recorded instance of a magnetic gas. While they are solids, not gases, compounds formed from actinide series elements exhibit similar magnetic properties when cooled.
The most powerful naturally occurring magnet is a compound, not a pure element: magnetite, or iron oxide. Naturally magnetized pieces of magnetite are called lodestones and have been used for their magnetic properties since ancient times. Large deposits of magnetite are magnetic enough to interfere with compasses.Learn more in Magnetism
The like ends of two magnets repel each other, such that a north pole on one magnet will repel a north pole on a second magnet. The same is true of two south poles on magnets.Full Answer >
Metals that are attracted to magnets include iron, nickel and cobalt. The majority of metals are not attracted to magnets, including copper, silver, gold, magnesium, platinum and aluminum. However, the metals that are not attracted to magnets may magnetize slightly when placed in a magnetic field.Full Answer >
Magnetism has been shown to affect plant growth positively. In addition to treating the seeds magnetically, water used to hydrate the plant can also be treated to boost its growth.Full Answer >
Magnetic energy is the energy within a magnetic field. This energy results in various metals either repelling or attracting each other.Full Answer >
