Role in a wide range of circular sink Kong Qiang magnet is introduced about the magnet you are feeling really very strange, so now I come to give you a few examples, see if you feel familiar with: home and children's toys, especially those robots, some large screw, looked at though it should be easy to feel can be plucked, discovered, but the real practice the following especially hard to get, feel like there's something in the absorption, the magnet is round sink hole of a special kind of types: screw holes magnet. After practice feel the magnet is very safe, dual protection, will make you more at ease, and the price of this circular sink hole magnet and very cheap, we compared to the tile shape magnet, tile shape of the magnet is the price of one yuan a piece, but the round sink hole magnet price is less than that so much, just a few cents, if the price is very cheap, there's another advantage of the magnet is in addition to the normal use, also can be used as ordinary magnet, caused a lot of convenience to our life. Electromagnet is the feature of magnetic control, that is, to the time of magnetic, will disappear when can disappear, in addition, as a result of the electromagnet is provided by the electric solenoid magnetic, when no current is not magnetic, so the electromagnet core need choose soft magnetic material, soft iron is the best choice. Also has a lot of is made of silicon steel, electromagnet iron core with insulation silicon steel sheet pile into each other, silicon steel sheet thickness usually is 0. 35 - - - - - - - 0. 5 mm flow, the eddy current in the circuit of long and narrow shape by smaller cross section to increase the resistance of the eddy current path; Silicon in silicon steel at the same time make material resistivity increases will also be able to reduce the eddy current effect. One thing to note, however, with the entire silicon steel piece will produce electromagnetic eddy current heating and can make the iron core affect motor power. Electromagnet coil is usually a copper or aluminum enameled wire. Magnet, powerful magnets, special-shaped magnets, magnet manufacturer,
