How can it be regarded as a valuable strong magnet, and how to distinguish Now many people know that strong magnet is more valuable, but they are not very clear about what kind of strong magnet is, because there are many kinds of magnets, and some people ask whether it is strong magnet if the [...]
If a magnet keeps doing work, will its magnetism be weakened or even disappear? There are many misconceptions about magnets and how they are magnetic. Since the magnetism of a magnet is invisible and intangible, it will be more abstract in the eyes of many people, and it is difficult to reflect it intuitively. First [...]
Magnetic Domains In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. That's why you can magnetize them. See how it works in this tutorial. Electrons are teeny tiny magnets. They have a north and a south pole and spin around an [...]
