Can Magnets Attract The Nails In The Water?
Jul 28, 2018

The magnet has a magnetic force between the N pole and the S pole, and the magnetic force cannot be blocked even if the object is spaced apart. For example, magnetic force can pass through paper or wood. However, if an object that refuses to be magnetized, like an iron type, the magnetic force cannot pass through. If the glass is used instead of an iron cup, the magnet cannot pick up the nail. If it is not iron but wood nails, of course, it cannot be sucked up.


The magnet is already an oxide and will not oxidize in water and will not change the internal structure.

A magnet is an object that attracts iron and generates a magnetic field outside it. A narrow magnet refers to a product of magnetite ore, and a generalized magnet refers to an object or device that is used to generate a magnetic field. The magnet acts as a magnetic dipole and can attract ferromagnetic substances such as metals such as iron, nickel and cobalt. [1] The determination of the magnetic pole is to hang a magnet with a thin wire, and the magnetic pole pointing to the north is called the north pole or the N pole, and the magnetic pole pointing to the south is the guide pole or the S pole. (If you think of the earth as a magnet, the earth's geomagnetic north pole is the S pole, and the geomagnetic south pole is the N pole.) The magnets are attracted to each other and the same poles are repelled. The guide is extremely attracted to the North Pole, and the guide is extremely repulsive to the guide, referring to the repelling of the North Pole and the North Pole.


The magnet  is made by pressing the ferroferric oxide powder with a filler and a binder. Some magnets are very magnetic, contain more Fe3O4, and some have weaker magnetic properties and less Fe3O4. Substances are mostly composed of molecules, molecules are made up of atoms, and atoms are composed of nuclei and electrons. Inside the atom, the electrons keep spinning and rotate around the nucleus. Both of these movements of electrons produce magnetism. However, in most substances, the direction of electron movement is different and disordered, and the magnetic effects cancel each other out. Therefore, most substances do not exhibit magnetism under normal conditions.


Ferromagnetic substances such as iron, cobalt, nickel or ferrite are different. The internal electron spins can be spontaneously arranged in a small range to form a spontaneous magnetization zone. This spontaneous magnetization zone is called a magnetic domain. After the ferromagnetic substance is magnetized, the internal magnetic domains are neatly arranged and aligned in the same direction, and the magnetic properties are strengthened to form a magnet. The magnet attracting process is the magnetization process of the iron block. The magnetized iron block and the magnet are attracted to each other in different polarities, and the iron block is firmly "sticked" to the magnet. We said that the magnet is magnetic.
