Special magnetic energy stored in powerful magnets and magnet strength has a special power, and electricity is not see and feel human, but its influence is everywhere. Magnet can be easily made suitable for the entire useful. We all know that there is something between the gravitational field. With the magnetic field, and the space around the field poles filled. The number of magnetic field lines to represent the idea of ??the size of a rectangular sheet magnet manufacturers, the more dense the magnetic field lines, the stronger the magnetic field, if the magnetic field lines will be weaker the more sparse. Powerful magnets would have been in the movement of charged particles in a magnetic field, called the Lorentz force effect. Due to a charged particle in a magnetic field is not the same as the strength of the magnetic force of the magnet Lorenzi was to distinguish its magnetic field strength unevenness. The Tesla amount that is devoted to the international unit of magnetic flux density. The flux density of the magnetic field that is depicted in the fundamental physical and magnetic field strength of the magnetic field that is portrayed adjuvant amount. Powerful magnets magnet knowledge understanding introduce rapid progress of industrial development, the application of powerful magnets not only penetrated into every aspect of the industry. What about some of the knowledge of powerful magnets surely we all know, a child used to play "toy", or you can call it the toy, then what is it powerful magnet? Here I introduce next: strong magnet is under no external magnetic field, can long maintain a magnetic object itself. Depending on the material can generally be maintained for 10 years magnets, powerful magnets available ferromagnetic materials such as iron, nickel or the like. Magnet is a generic term that refers to having magnetism, the actual components may not include iron. Relatively pure metallic state does not have a strong magnetic iron only near powerful magnets will generate a magnetic induction, the general added powerful magnets inside the other impurity elements such as the addition of carbon to stabilize the magnetic square sheet magnets Which is good, but this would reduce the freedom of the electronic conductivity is not easy, so when the current through the light bulb lit up, with magnetic iron is a common element, but many other elements have a stronger magnetic square magnet, like a lot of powerful magnets is neodymium, iron, mixing boron made. In addition, the materials required to use powerful magnets with a broad high long hysteresis loop, because of this, when the external magnetic field is zero, in order to still have a relatively strong magnetization; if you want to magnetization becomes zero, relatively strong external magnetic field is applied demand.
