Magnets are generally sold in hardware stores, and there are hardware stores in or around your local market where you can buy magnets. Hardware stores specialize in selling work tools, construction hardware, home hardware, and some appliances for industry.
Magnets, also known as iron absorbers, in the surrounding and their own internal presence of magnetic field objects or materials, divided into two categories of natural and man-made. Artificial magnets are usually made of metal alloys and have strong magnetic properties.

Safe handling of magnets:
Always be very careful as magnets can attract themselves together and may pinch your fingers. The magnets may also damage the magnets themselves by bumping into each other when they are attached to each other.
Keep magnets away from items that are easily magnetized, such as floppy disks, credit cards, computer monitors, watches, cell phones, and medical equipment. For larger magnets, add plastic or cardboard spacers between each piece to ensure that the magnets can be easily separated.
Magnets should be stored in a dry, temperature controlled environment.
Small hardware stores have, is that the screen window magnetic nail, also called screen window magnetic button, square with two exposed iron bars, can be sucked on top of any ferromagnetic material; inside is the magnet, usually inexpensive ferrite.
If you want to buy a strong magnetic material, like sintered neodymium iron boron, you have to order it from a professional manufacturer.

Neodymium magnets
(Neodymiummagnet), also known as NdFeB magnets, with the chemical formula Nd2Fe14B, are man-made permanent magnets with the strongest magnetic force so far.
The neodymium magnet was invented in 1982 by Sumitomo Special Metals Corporation's Sagawa Makoto and others, and its chemical formula shows that it is mainly composed of neodymium, iron and boron and other chemical elements. It has the potential to replace traditional pure iron magnets, alnico alloys and samarium cobalt magnets in many areas such as electric motors, instruments and meters, the automotive industry, the petrochemical industry and magnetic healthcare products. We are able to produce various shapes: such as disk magnets, ring magnets, rectangular magnets, arc magnets and other shapes of magnets.
Neodymium magnets are used in a wide range of electronic products, such as hard disks, cell phones, and headphones.

Magnets are one of the common goods sold in quite a few infernal stores.
Magnets
Magnets are composed of iron, cobalt, nickel and other atoms, the internal structure of its atoms is relatively special, itself has a magnetic moment. Magnets are capable of generating magnetic fields and have the property of attracting ferromagnetic substances such as iron, nickel, cobalt and other metals.
Types of magnets: shape magnets: square magnets, tile magnets, shaped magnets, cylindrical magnets, ring magnets, round sheet magnets, magnetic bar magnets, magnetic frame magnets, attribute magnets: samarium cobalt magnets, neodymium iron boron magnets (powerful magnets), ferrite magnets, alnico magnets, ferrochrome cobalt magnets, industry magnets: magnetic components, motor magnets, rubber magnets, plastic magnets and other types.
Magnets are divided into permanent magnets and soft magnets, permanent magnets are coupled with strong magnetism, so that the spin of the magnetic material and the electron angular momentum into a fixed direction of the arrangement of soft magnets is coupled with electricity. (It is also a method of adding magnetic force.) When the current is removed, the soft iron will slowly lose its magnetism.
